To maintain a working SERVOPACK, there are a series of procedures to follow for inspection. The following steps should be followed at least once a year in order to ensure the best condition for your machine.

Upgrading From FANUC C Series Servo Amplifier to α Series
If you experience a system failure due to a Fanuc C series servo amplifier, (A06B-6066-H002, H003 etc.) you may feel like your only option is to replace it with the same exact unit. However Fanuc also offers the α series servo amplifiers which features improvements over the C series. In most cases you can replace your C series servo amplifier with the α series servo amplifier that has the identical final four numbers of the C series model number. The chart below outlines this:
The advantages of replacing your C series amplifier with an α series amplifier are:
- A built in power supply
- A second interface, type B, as well as the more conventional type A interface
- Updated power device, intelligent power module, to reduce power loss and increasing reliability
α series amplifiers are also designed with the same dimensions as the C series so that you can install them into your current system easier.

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. Search for more FANUC motors/drives on our website.
MRO Electric and Supply maintains a comprehensive stock of new and used FANUC CNC and FANUC Robots parts. If you need a FANUC replacement part, please call 800-691-8511 or email sales@mroelectric.com.
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.
MRO Electric stocks a large number of FANUC CNC Products, and provides repair services as well. For more information or to request a quote, please call 800-691-8511 or email sales@mroelectric.com.
Simodrive E/R Module Fault – Troubleshooting
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.
