The A06B-6079-H106 is a 1-axis Alpha Servo Amplifier Module that uses a Type A or Type B interface. When installing the module, observe the ambient temperature and output rating requirements. The continuous output rating or continuous operation period of some amplifiers may fall as ambient temperature increases. If the amplifier is used continuously with an excessive load applied, the amplifier may be damaged. Before operating the amplifier for the first time, mount and adjust the speed and position detectors so that an appropriate waveform is obtained. If this is not done, the motor may not rotate normally or the spindle may fail to stop as desired.
If the motor makes any abnormal noise or vibration during operation, stop operation immediately. If operation is continued, the A06B-6079-H106 could become damaged. Take corrective action before continuing with operation. Be sure to only replace the battery when the servo amplifier is on. If the battery is replaced while the power is turned off, the stored positioning data will be lost. Also ensure that the battery connector is correctly inserted. The cover on the front of the A06B-6079-H106 carries a label indicating the specification code. When mounting a previously removed front cover, take care to mount the correct cover to the right unit.
You can observe an instantaneous motor current value on the A06B-6079-H106 by checking the voltage across a reference voltage check pin and a motor current check pin with an oscilloscope. You cannot use a device such as a multimeter to find the correct values. To check the power supply voltage, use the reference voltage check pin and the power check pin with a multimeter, oscilloscope, or similar. This will tell you the power supply voltage for the control circuit in the amplifier.

Using either the panel’s software or its touch panels, a user can control 16 different levels of screen brightness.
The HMIGTO5310 weights precisely 2 kg. It measures 272.5 x 214.5 x 57 mm (W x H x D). The HMIGTO5310 can be mounted by using 4 screw clamps with flush mounting.
The HMIGTO5310 supports a large number of downloadable protocols, including the Modbus TCP, Siemens Simatic, Rockwell Automation / Allen Bradley, Omron Sysmac, Mitsubish Melsec, FIPWAY, Modbus Plus, Uni-TE, and Modbus. The panel supports a number of integrated connection types, some of which include the Ethernet RJ45, the USB 2.0 ports, COM2 serial links, and a COM1 serial link. When using the COM2 serial interface, be aware that the serial port is not isolated. The signal ground and frame ground terminals are connected inside the panel. There is risk of electric shock if precautions are not taken. When using the signal ground terminal to connect an external device to the panel, verify that a short circuit loop was not created when you set up the system. Connect the #8 signal ground terminal to remote equipment when the host PLC unit is not isolated. Connect the #8 signal ground terminal to a known reliable ground connection to reduce the risk of damaging the circuit.
When setting up RS-485 communication, the cable diagram for some equipment may require polarization on the terminal side. This terminal does not require any special setting as it handles polarization automatically.
The Schneider Electric / Modicon 140CPS11420 is a Power Supply Module in the Quantum automation platform. It can use a summable or standalone power supply type. The module has an internal output overvoltage and overload protection. It comes in a standard module format and weights 0.65 kg. When in a standalone configuration, the 140CPS11420 uses a maximum current of 11 amps. In a summable configuration, the module has a maximum current of 20 amps. Its internal power dissipation is less than 12 watts at a full load.
A normally closed relay contact rated at 220 volts AC, 6 amp / 30 volts DC, 5A is available on terminals 1 and 2 of the power terminal strip. This contact set may be used to signal input power Off. The relay will de-energize when input power drops below 70 volts AC, when the input voltage is set to 115 volts AC, or 140 volts AC when the input is set to 230 volts AC. Its output to the Bus is 5.1 volts DC. No minimum current is required. The module’s input frequency can range from 47 – 63 Hz. the 140CPS11420’s input voltage total harmonic distortion is less than 10% of the fundamental root mean square value. The input power interruption is no less than 1 second when in a 1/2 cycle at full load, and at the minimum rated line voltage and frequency.
Remove the power line prior to insertion or removal of the module.Use only compatible combinations of summable and standalone power supplies in the Quantum back plane as stated above. If these precautions are not taken, serious injury and/or equipment damage could occur.
The FANUC A06B-6079-H206 is a 2-axis servo amplifier module. Its standard dimensions are 380 x 60 x 307 mm. The Status display is a 7-segment LED that indicates the operation status on the module. If the Status display is not on then the power is not turned on, the cable has a power connection, or the module is defective. If the module is defective, replace the fuse or servo amplifier. If there is a single middle line on the display, the control power supply is waiting for the ready signal. If all the outside lines are on, the servo amplifier is ready to operate and the servo motor is supplied with power. If an alarm is issued on the servo amplifier, a value other than “0” and “-” is displayed.
A pin board can be used with the A06B-6079-H206. The use of a check pin board allows you to observe the signals inside the servo amplifier. CN1 and CN2 are wired with a one to one correspondence. The connector pin numbers correspond to the check pin numbers. You can observe an instantaneous motor current value by observing the voltage across a reference voltage check pin and a motor current check pin with an oscilloscope. Note that you cannot use a device as a multimeter to observe the correct values. You can also measure the voltage across a reference voltage (0V) check pin and a power check pin with a multimeter, oscilloscope, or the like to observe the power supply voltage fr the control circuit inside the servo amplifier. If the measured voltage is within 5% relative to the nominal voltage, the measured voltage is considered acceptable.
A special lithium battery can be installed in the A06B-6079-H206. Be sure to install the battery with correct polarity, otherwise it may overheat, blow out, or catch fire. Use the factory-installed protection sockets in the unused connector after installing. This can help prevent the battery from short-circuiting.

External power is not necessary for this module. On its front panel, it has a total of 32 green LEDs that indicate the status for each point. This module is of standard size and can fit into any Modicon Quantum backplane easily.
Below is the Wiring Diagraph for the Modicon DDI35300:
The UD55 Cloning Small Option Module can store up to eight parameters-sets which contain all the read–write parameters for a Drive, and include those in Menus 16 & 20, when applicable. These parameter sets can be individually recalled for loading onto the same or another drive.
The cloning of drives can only be performed when the operating mode (Open-loop, Closed-loop Vector, Servo or Regen) of the destination drive is the same as that of the source drive. The UD55 must be fitted in the small option module bay of the Unidrive. All connections to the drive are made by a multi-way connector. Connections from external equipment are made to a plug-in 16-way screw-terminal block on the option module. Some parameters have a profound effect on the operation of the Unidrive. They must not be altered without careful consideration of the impact on the controlled system. Measures must be taken to prevent unwanted changes due to error or tampering.
1. Disconnect the AC supply from the Drive.
2. Check that the exterior of the UD55 is not damaged, and that the multi-way connector is free from dirt and debris. Do not fit a damaged or dirty UD55 in a Unidrive.
3. Remove the terminal cover from the Drive.
4. If a small option module is already fitted in the Unidrive, grip the recesses at the ends of the module and pull the module out of the Drive. Keep the module for re-fitting.
5. Position the multi-way connector on the rear of the UD55 over the connector in the Drive (see figure below), and press on the thumb pad to push the UD55 into place.
If the Drive trips and a trip code is displayed while this procedure is being followed, ensure that all the required parameters have been set up in the source Drive and that new parameter values have been saved.
If a small option module was fitted in the Drive, its associated Menu 16 parameters will be copied to the UD55 in addition to the parameters in the other menus. 1. Insert the UD55 in the source Drive (refer to Chapter 3, Inserting theUD55 in a Drive). 2. Ensure terminal 30 of the Drive Signal connector is open-circuit so that the Drive does not become enabled when powered-up. 3. On the UD55 connector, connect terminal 40 directly to terminal 41 to enable the save function (see Figure 2). 4. Re-fit the terminal cover to the Drive. 5. Connect the AC supply to the Drive. 6. Decide which parameter-set number is to be used in the UD55. If a parameter-set already contains parameter values, these will be over-written without warning. It is recommended that a record is made of at least the following for each parameter-set number:
• A means of identifying the configuration of the source Drive
• The model size of the source Drive
• The type(s) of option module(s) fitted
• Motor ratings 7. Set parameter .00 (in any menu) at 300X, where X is the required parameter-set number (1 to 8). 8. Press . The parameter values are now copied (saved) to the UD55.
Saving takes approximately 5 seconds. When it has finished, parameter .00 returns to zero. 9. It is recommended that parameter 11.38 is set at the number of the parameter-set (value of X in step 7) and the value of parameter 11.40 UD55 full parameter check sum noted, as a means of identifying the parameter-set at a later date. 10. Disconnect the AC supply from the Drive. 11. Remove the terminal cover. 12. Disconnect the link between terminals 40 and 41 on the UD55 connector. 13. Remove the UD55 from the Drive. 14. If a small option module was previously fitted in the Drive, re-fit the module. 15. Replace the terminal cover. 16. The Drive can now be used.

Often people have difficulty installing a replacement drive that we send out, and normally it just takes the troubleshooting tips from the manual to get them up and running. However, the manual isn’t always the easiest to find or sort through, so below we’re posting the Siemens Micromaster 420 Troubleshooting section from the manual which should help anyone who is working to get the issues with their drive sorted out. To check out the full list of Siemens Micromaster drives on our site you can visit the link here or email firstname.lastname@example.org
Here are some basic principles for troubleshooting a FANUC motor circuits with meter or megohm meter. This procedure will show you how to test for shorts in windings, cables, or opens. Before starting to test, make sure to turn all all the power sources to the machine and then disconnect the 3-phase motor lines from the drive end. Visually confirm that there are no problems with the cable and then begin testing.
Testing for a short to ground:
Using an Ohm meter: Disconnect all power from machine. Check all three wires at T1, T2, and T3 (all three phases) to the ground wire. The readings for this should be infinite, and if it is zero or reads any continuity then there is a problem with the motor or the cable. For this disconnect the cable and check each separately. Be sure to make sure leads on both ends are not touching anything, including the other leads. Most servo motor shorts can be ready with a regular quality meter going to at least 10 megaohms.
Using a Megohm meter: Disconnect all power from machine. Check all three wires at T1, T2, and T3 (all three phases) to the ground wire. Reading should be between 600-2000 Megohms. Most shorts will be below 20 Megohms. Be careful not to touch the leads or the wires to anything when taking the reading because it can give a false reading. There should be about 1000 Ohms of resistance for each volt of incoming power, but this is not a standard rule. If it is 230meg to 600meg there may be deterioration in the cable.
Testing for Open or Short in the windings:
Using an Ohm meter: Disconnect all power from the machine. Put meter on ohms and test T1 to T2, T2 to T3, and T1 to T3. The range should be between 0.3 and 2.0 ohms, with most being at about 0.8 ohms. If it is zero there is a short between the two phases. If it is an open the reading will be infinite or well above 2,000 ohms.
Cable and plug notes: Often times the connector on the cable to the motor will get coolant in it. You can dry it out an retest, if it is still bad the inserts will get burn marks in them and cause a slight short, so they need to be replaced. If it is a DC motor, check the brushes. There should be 3-4 round caps to remove around the motor. Under these there is a spring with a square block (brush). Check to see how much is left, they may need to be replaced.
MRO Electric has a large stock of FANUC motors available. If you would like a replacement or spare, or if you have any questions, please call 800-691-8511 or email email@example.com.
1. Be certain your input voltage source, motor, and drive name plates are all marked either 230V, 460V, or 575V. Other voltages can be used, but they require additional programming.
2. Mount drive on vertical surface with adequate space for air circulation.
3. Remove front cover, fit conduit to bottom plate, and connect power and ground wires.
Caution: Be certain you connect power to terminals L1, L2, and L3 only, or serious damage will result. Connect motor to T1, T2, and T3 only.
Installation of External Run/Stop Switch and Speed Potentiators:
Important: Complete the Installation and Keypad Operation before attempting external control.
Disconnect power, remove cover, and wait for “CHARGE” light to go out.
Connect a switch to terminals 1 and 11 using two conductor shielded wire. This circuit is 24Vdc, very low current; use a quality rotary or toggle switch (all wire should be 14-18AWG). Connect the shield to terminal 12 on the drive end only.
Install a single conductor “jumper wire” between drive terminals 5 and 11.
Connect a manual speed potentiometer rated 2000-3000 ohms, 1 watt minimum, using three conductor shielded wire, with shield connected at terminal 12. Connect wires to the potentiometer. Trace wire closest to the top and connect to terminal 17. Trace center wire of potentiometer through and connect to terminal 16. The remaining wire will be connected to the trim pot in step 5.
Connect a trim potentiometer rated 2000-3000 ohms, 1 watt minimum, as close to the drive terminals as possible. Viewing the potentiometer from the back, connect a single conductor wire from the left terminal to terminal 15 of the drive. Connect a short jumper wire between the center and left terminals. Connect remaining wire from manual speed pot as shown.
