Control Techniques UD70 Installation

UD70 Module

The Control Techniques UD70 Application Module with Modbus Plus interface for Unidrive is supplied in a large
option module package. The Modbus Plus interface uses the UD70
Applications Module card as a host, effectively making it a UD76 option module. An 80C152 processor and System Protocol Chip handle all Modbus Plus network activity, and a Dual-Port RAM interface is used to transfer data between the Modbus Plus layer
and the UD70.
The UD70 Application Module retains full functionality when it is part of the UD76 module, allowing the user to download normal DPL application programs. No program modifications are
required to allow existing DPL programs to run. A different UD70 operating system file (“MBPLUS.SYS”) is used, and the UD70 has this system file pre-loaded. The UD70 also uses a second DPRAM interface to transfer data to and from the drive.

To install the UD70 Application Module, isolate the drive from the main supply and allow 5 minutes for the DC bus to discharge. Then insert the UD70 with the black tab facing up so that it clicks firmly into place. To remove the module, pull on the black tab and the unit will disengage.

Fanuc A06B-6050-H103 Servo Jumper Settings

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.

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.
