Micromaster 420

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.

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.

 

List of Sinamics S120 Faults and Alarms

 

F01000:  Internal software error

F01001:  Floating Point Exception
Message Value: %1
Drive Object: All objects
Reaction: OFF2
Acknowledge: POWER ON

Cause: It was not possible to download the firmware to a DRIVE-CLiQ component
Remedy: Check the selected component number
Check the DRIVE-CLiQ connection
Save suitable firmware file for download in “/siemens/sinamics/code/sac/”
Use a component with a suitable hardware version
After POWER ON has been carried out again for the DRIVE-CLiQ component,                               download the firmware again. Depending on p7826, the firmware will be                                       automatically downloaded.

A01006: Firmware update for DRIVE-CLiQ component required
Message Value: Component number: %1
Drive Object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The firmware of a DRIVE-CLiQ component must be updated as there is no suitable firmware or firmware version in the component for operation with the Control Unit.
Alarm value (r2124, interpret decimal): Component number of the DRIVE-CLiQ component
Remedy: Firmware update using the commissioning software: The firmware version of all of the components on the “Version overview” page can be read in the Project Navigator
under “Configuration” of the associated drive unit and an appropriate firmware update can be carried out.
Firmware update via parameter:
– Take the component number from the alarm value and enter into p7828.
– Start the firmware download with p7829 = 1.

A01007: POWER ON for DRIVE-CLiQ component required
Message Value: Component number: %1
Drive Object: All objects
Reaction: NONE
Acknowledge: NONE
Cause:  A DRIVE-CLiQ component must be powered up again (POWER ON) (e.g. due to a firmware update). Alarm value (r2124, interpret decimal): Component number of the DRIVE-CLiQ component. If the component number is 1, a POWER ON of the Control Unit is required. 
Remedy: Switch off the power supply of the specified DRIVE-CLiQ component and switch it                   on again.
For SINUMERIK, auto commissioning is prevented. In this case, a POWER ON is                           required for all components and the auto commissioning must be restarted.

A01009 (N):   CU: Control module overtemperature
Message Value: –
Drive Object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The temperature (r0037[0]) of the control module (Control Unit) has exceeded the specified limit value.
Remedy: Check the air intake for the Control Unit.
Check the Control Unit fan.

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.

Control Techniques Commander SE HF Trip Codes

Commander SE
Commander SE

The Control Techniques Commander SE Microdrive series is an AC open loop vector that provides great flexibility as well as a small footprint.  Although this series is reliable you may encounter one of the HF Trip codes listed below.  These codes are a result of an internal error in the drive.  Most often these trip codes can be resolved by powering down and allowing the drive sit for 5 minutes before powering up again.

If the HF Fault code does not clear then your drive will likely require a repair.

Fanuc Alarm 466 – Z Axis: Motor/Amp Combination

We just shipped out a Fanuc A06B-6096-H207 Servo Amp unit to a customer, and as soon as they installed the amplifier they got a Fanuc Alarm 466 which refers to the Z Axis: Motor/Amp Combination. This is obviously somewhat distressing for a customer to buy a replacement unit and immediately get an alarm when it is installed, but fortunately this is an easy fix.

This Alarm 466 comes from the replacement amplifier having newer servo software than the unit that it is replacing. As Fanuc has made newer units they’ve upgraded the software/hardware within these amplifiers, so you just need to reset a parameter to reboot the configuration and clear the 466 Alarm. The steps are below.

– Put the machine in Emergency Stop
– Go to parameter 2165 on the control
– Set all the values to 0
– Take the machine out of emergency stop

Once these parameters are changed and the machine is rebooted, the alarm will clear and the amplifier will initialize. We also have pictures below to confirm that you know what to look for. For any additional help, call us at 800-691-8511 or email sales@mroelectric.com.

Simodrive Fault Code 7 – LT Module

Recently we had a customer with a 6SN1123-1AA00-0CA1 Simodrive LT Module that they were getting a fault code 7 on. This fault code has to do with the speed controller being at it’s limit. This alarm was coming up randomly for them, and would go away temporarily if they swapped out their motor with a spare. The controller card that they were using was a 6SN1118-0AA11-0AA1 card, which was determined as faulty once the other components were tested. Once the card was replaced, the customer was able to get up and running.
