Modicon 140AVI03000

Modicon Quantum 140AVI03000 – Product Spotlight

The 140AVI03000 is a Analog Mixed Current/Voltage Input Modules that is part of the Modicon Quantum series. This Analog In 8 Channel Bipolar Modules accepts a mix of current and voltage inputs. Jumpers are required between the input and sense terminals for current inputs. The 140-AVI-030-00 contains a total of 18 LEDs. The “Active” LED remains on and green when Bus communication is currently present. The “F” indicator will light up red when an error external to the module has been detected. The green LEDs 1 through 8 will turn on when the indicated point or channel is ON. The red 1 through 8 LEDs when light up for two reasons. Either the indicated channel is out of range (1 – 5 Volts), or a broken wire condition has been detected (4 – 20 mA).

To prevent improper fault indications, unused inputs should have the + (plus) and – (minus) inputs tied together and be configured for a bipolar input range. Unwired inputs can cause invalid readings. When configured for voltage inputs (no jumper is installed between Input (+) and ISENSE terminals), a broken field wire can cause readings to be non-zero and unpredictable. The field wiring terminal must not be removed when the module is in operation.

The following figure shows the 140-AVI-030-00 Wiring Diagram.

For external wiring, the user should supply the current and voltage sources, and installation and calibration of the fuses are at the discretion of the user. It is recommended that shielded cables are used, and twisted shielded cables should be used in noisy environments. The shielded cables should be connected to the PLC’s ground. A shield bar should be used to connected the shielded cable to the ground. If you are field wiring the 140AVI03000, the maximum wire size is 1-14 AWG or 2-16 AWG and the minimum wire size is 20 AWG.

Yaskawa V1000

Yaskawa V1000 – Compact Vector Control Drive

The Yaskawa V1000 is a compact current vector drive with dual microprocessor logic. There are 3 primary models: 200V 3-Phase Input, 200V Single-Phase Input, and 400V 3-Phase Input.  It is possible to run the drive without connecting the digital I/O wiring.

It is important when installing Yaskawa V1000 drives that proper electrostatic discharge (ESD) procedures are taken. Failure to comply could result in an ESD discharge that could damage the drive circuitry. If the drive is being operated at low speeds, the cooling effects are diminished and motor temperatures can increase which can lead to overheating. Continuously operating an oil-lubricated motor in the low speed range may result in burning.

A dynamic braking resistor can be used with the V1000 series. Dynamic braking helps bring the motor to a smooth and rapid stop when it is working with loads of high inertia. As the drive lowers the frequency of a motor with high inertia connected, regeneration occurs. This can cause over-voltage when the regenerative energy flows back into the DC bus capacitors. A braking resistor can help prevent these overload errors from occurring.

The drive functions are devided into 2 primary groups that are accessible through the Yaskawa V1000’s digital LED operator. Drive mode allows for motor operation and parameter monitoring. Parameter settings cannot be changed when functions are accessed in drive mode. However, alarm information and history can be accessed in drive mode. Programming mode allows access to the setup. There you can adjust and verify drive parameters as well as Auto-Tuning. The drive will not allow motor operation changes such as start and stop when the LED is accessing a function Programming mode. The V1000 is set to Drive mode when it is first powered up. The Up and Down arrow keys can be used to switch displays.

Modicon 140CRA31200 RIO Drop E/IP Adapter – Product Spotlight

The 140CRA31200 is a Ethernet RIO drop adapter in the Modicon Quantum series. It has 3 ports and uses the Ethernet IP/Modbus TCP communication port protocol. It can handle two integrated connection types: the Ethernet IP/Modbus TCP through the service port or through the device network. It is compatible with the 140CRP31200.

The 140CRA31200 has a number of local signalling channels. 1 green LED for RUN, 1 green/red LED for module status, 1 green/red LED for network communication status, and 1 red LED for I/O. This adapter module consumes one slot in the main (first) rack of the in Quantum remote drops. The extended (second) rack in a Quantum remote I/O drop does not require an adapter.

To set the location of the Ethernet remote I/O drop on the network, use the rotary switches on the front of the 140CRA31200 before you apply power to the module and before you download the application. The values that are set are applied during a power cycle. If the switch settings are change after the module has powered up, the Mod Status LED is activated and a mismatch message is logged in the module’s diagnostic system.

Because new values on the rotary switches are implemented on at the next power cycle, it is recommended that you set the values before starting the module. Valid values are from 00 to 159. These rotary switches can be manipulated on the 140CRA31200 with a small flat tipped screwdriver, and no software is required to configure or enable the rotary switches. Do not use the Stored and Clear IP settings on the Ones rotary switch, and keep in mind that the functionality of these settings do not apply to remote I/O installations.

FANUC A06B-6079-H206 – Beyond the User Manual

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.

UD55 Small Option Module for Control Techniques Unidrives

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.

UD55 Installation

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.

Saving Parameters

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.
