Enhance System Performance with Modicon Quantum I/O Modules

Substation I/O modules for direct 125 Vdc control
Quantum I/O modules are available for direct connection to critical 125 Vdc battery powered equipment such as circuit breakers, protective relays, transformers and capacitor banks.

  • Built-in high transient noise immunity ensures reliable operation in harsh 125 Vdc environ- ments.
  • The 125 Vdc 30A high current output module eliminates expensive high current interposing relays used in breaker tripping and closure.
  • The solid-state 125 Vdc low current output module ensures long life and trouble-free operation in higher frequency 125 Vdc switching environments without the use of expensive external snubbing circuitry.
  • Over-current/ short circuit diagnostics and protection on all solid state 125 Vdc outputs reduce downtime by ensuring quick identifi- cation of circuit prob- lems and fast repair.
Special Purpose Module Characteristics
Latch/Interrupt module for time critical applications
The Quantum Latch/ Interrupt module is a multi-purpose high speed input, latch,
and interrupt module combined, which is configurable through programming software. Interrupt handling instructions are part of the 984 Ladder Logic instruction set. Quantum throughput performance for 2 interrupts is typically 1ms.
High speed counters don’t miss a pulse
Quantum high speed counter modules have the ability to count pulses at speeds much faster than the Quantum controller can directly do by itself. These modules automatically report the current count to the Quantum controller every scan.
Simple ASCII exchanges
The Quantum ASCII module is a general purpose ASCII interface that provides the ability to communicate and ex- change data with devices including printers, bar code readers and scanners, weigh scales, and meters. This module is designed for relatively simple point to point ASCII communications, with ASCII messages stored inside the module triggered by logic within the Quantum controller.

Sinamics 6SL3040-1MA01-0AA0: Beyond the User Manual

The Siemens 6SL3040-1MA01-0AA0 is a Sinamics Control Unit CU230-2 PN. It is designed for use with several drives. It is a control central modules in which the closed-loop or open-loop functions are implemented for one or more line modules and/or motor modules. The number for VFD drive depends on the required performance, the required additional functions, and the required operating mode (servo, vector, or U/f). The software and parameters are stored in a plug-in memory card, and the option slot can be used to expand the number of terminals or adapt other communication interfaces to the higher-level control.

6SL3040-1MA01-0AA0
6SL3040-1MA01-0AA0

If your application requires more than one control unit, the number can be increased accordingly and interconnected via the Profibus. The 6SL3040-1MA01-0AA0 communicates with its associated components, like motor modules, line modules, sensor modules, and terminal modules, via the internal system’s DRIVE-CLiQ interface. The module has 12 isolated digital inputs, and 8 non-isolated digital inputs/outputs.

With the 6SL3040-1MA01-0AA0, an open input is interpreted as “low”, and terminal M1 must be connected so that the digital inputs (DI) can function. This can be completed by either providing the ground reference for the digital inputs, or by using a jumper to terminal M. If at any time the 24V power supply is briefly interrupted, the digital outputs are deactivated. If at any time the memory card is withdrawn or inserted while the 6SL3040-1MA01-0AA0 is in operation, then data can be lost and a plant standstill could occur. Only withdraw the memory card when the control unit is in a no-voltage condition. Electrical fields and electrostatic discharge can also result in the memory card being damaged, so observe ESD regulations when handling it.

Sinamics S120 Fault Codes and Alarms, Part I

There are several differences between faults and alarms on Sinamics S120 Drives.

TypeDescription
FaultsWhat happens when a fault occurs?
- The appropriate fault reaction is initiated
- Status signal ZSW1.3 is set.
- The fault is entered in the fault buffer.

How are faults eliminated?
- Remove the original cause of the fault
- Acknowledge the fault
AlarmsWhat happens when an alarm occurs?
- Status signal ZSW1.7 is set.
- Alarms are "Self Acknowledging" meaning they are reset when the cause of the alarm has been eliminated.

Siemens Micromaster 420 Faults and Alarms

A blog we posted earlier this week about the Micromaster 420 troubleshooting referenced the Faults and Alarms list for the Micromaster series, so we decided that it would make sense to make the list of Micromaster 420 Faults and Alarms directly available. This is from the corresponding manual for the Micromaster 420 series, but it is buried within the manual which most people most likely don’t even have. Hopefully this helps with your troubleshooting.

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.

Troubleshooting a Fanuc Motor

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 sales@mroelectric.com.

A06B-6058-H005: Beyond the User Manual

Generally, Fanuc AC servo motors, like the A06B-6058-H005, have no parts that wear off or that must be replaced periodically, unlike DC servo motors, which have brushes that must be replaced. However, you should perform period maintenance for servo motors so as to keep their initial performance as long as possible and to prevent breakdowns. AC servo motors have precision sensors — their incorrect use or damage caused during transportation or assembling can result in breakdowns or accidents.

It is recommended that you inspect servo motors periodically, and of course we offer a 12 month warranty on all Fanuc products purchased from MRO Electric.

Receiving and Keeping the A06B-6058-H005

When you receive a A06B-6058-H005 module from MRO Electric, make sure that the motor is exactly the one you ordered, in terms of model, shaft, and sensor specifications, and make sure that no damage has been caused on the motor. Servo motors should be kept indoors as a rule. The storage temperature range is -20 to +60 Celsius. Do not place or install AC servo motors in a place where it is extremely humid and dew is prone to form, where there are steep changes in temperature, where there is constant vibration, or there is lots of dust and trash. Constant vibration may cause damage to the shaft bearings.

Daily Inspection Procedures

Before starting operation, or periodically (once a week or month), you should inspect the AC servo motors for vibration and noise, outside damage, stains and smudges, overheating.

Check the motor for abnormal vibration by hand, and noise by ear when the motor is not rotating, rotating at low speed, and accelerating and decelerating.

Check the Pulsecoding cover (read plastic) for crevices and the motor surface (black coating) for scratches and cracks. If you find a crevice on the Pulsecoder cover, you should replace it. If there is a scratch or a crack on the motor surface, the user should repair it by himself as required. If coating has come off, dry the portion of interest or the entire surface and coat it with paint for machines such as urethane paint.

Check the motor surface and bolt holes for oil or cutting fluid. Wipe off oil and cutting fluid on the surface periodically. Oil or cutting fluid can damage the coating by chemical reaction, possibly leading to failure. Also check how such liquid leaks onto the motor, and repair if needed.

Check to see if the motor is too hot during normal operation. Attach a thermolabel on the motor surface and check it visually to see if the motor becomes too hot during normal operation.
