When there is a critical condition detected in your Control Techniques UNIDRIVE, the drive will continue to operate, but the lower display’s status indication will be replaced by an alarm indication. When an HF trip takes place, the Drive Healthy relay will open and serial communications will not function. It is important to give attention to alarm indications, because if an issue is not corrected, the drive could trip.

Refer to the guide below to help identify what kind of error your UNIDRIVE may be experiencing. A comparison chart with status indications is also provided to help identify what happens at each stage of operation.

Upgrading From FANUC C Series Servo Amplifier to α Series

Joe Kaminski Leave a comment

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.
