When troubleshooting the Schneider Electric 140CPU11302 Module, it’s important to know the number of times the Run LED blinks for each type of error, along with the crash codes possible for that group. All the crash codes are in hexadecimal form for this particular module. The list of possible LED Descriptions and Error Codes are as follows:
When replacing a Fanuc A06B-6050-H103 Servo unit you should check to make sure the replacement servo has the same top board, part number A20B-1000-0560. After this part number there will be a “/” and then something similar to “05A” which denotes the revision of the board. Ideally you would match your original unit with a replacement unit that has the same board, but if that’s not possible then all you would need to do is reconfigure the jumpers on the board. The table below shows how to get this set up so you can get your servo back up and running right away. Search for more FANUC motors/drives on our website.
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.
We had a customer who was getting an alarm on their Simodrive E/R Module with a fault on the machine after the hydraulic was put on. They had tried resetting the machine but the same alarm would come back up. The Simodrive part number was 6SN1145-1BA01-0DA1, the only light on it was the green LED and the terminals were both reading 27VDC. The customer was considering buying a new drive but wanted to check to see if there was some way of resolving the issue without buying a whole new Simodrive.
Based off the LED configuration that the customer was having, we determined that the external enable signal 63 was missing, so they needed to double check their connections. When the customer checked, the contact from the hydraulic connector was not making a good connection. All the customer needed to do was replace the contact kit and restart the machine which got them up and running. We would highly recommend always double checking the connections on a unit before replacing it, because there can often be a simple issue that doesn’t require the full unit to be replaced.
