NI SoftMotion Faults and Warnings

NI SoftMotion Module Help

Edition Date: August 2013

Part Number: 371093P-01

»View Product Info

The NI SoftMotion VIs and functions can return the following faults and warnings. NI SoftMotion fault codes are subdivided such that the top four digits are used to identify the source of the fault as follows:

  • 0000: generic fault
  • 01F9: NI specific fault
  • 006A: AKD servo drive fault

The bottom four digits follow the DS 402 spec error code definitions. For example, in the NI SoftMotion fault code of 01F98130 the digits 01F9 indicate that the fault is an NI-specific version of the 8130 error code (NI 951x Heartbeat Communication Fault). Error codes that are in the range of FF00 to FFFF are manufacturer specific and can be used to provide fault information for faults that do not have DS 402 counterparts, such as 01F9FF85 (User-Defined Variable Deployment Fault). When reading faults from NI SoftMotion using Read Faults, NI SoftMotion returns the entire fault code. When reading faults using the Interactive Test Panel dialog box, only the bottom four digits are displayed.
