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.

If you have just received the Schneider 140 NOE 771 xx module but have not yet programmed it with an Ethernet configurable extension, you will need to assign an IP address to your module. In this guide you’ll receive information about assigning a 140 NOE Module Ethernet Address Parameter.
Using the BOOTP Lite software utility you can assign IP address parameters. One thing to note, however, is that with the modules 140 NOE 771 01, -11, and NWM 100 00 you can assign the IP address using web pages.

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.

We often have people who are having issues with their current drive setup but can’t confirm that a specific drive in their system is the issue. They are all but sure, but understandably want to confirm the problem before buying a replacement from us, so we have a set of troubleshooting procedures issued from Siemens that we can send out so that people can confirm that they have a problem. Last week a customer was replacing a Siemens 6SN1145-1BA02-0CA1 module and wanted to troubleshoot their I/R module, so we’ve listed the troubleshooting procedures in the table below to help with Simodrive E/R Troubleshooting. For a full list of the Siemens Simodrives that we have available you can visit the section on our website here.
