What it means

Drive unit has the wrong type code: the type code read from the drive unit of the indicated joint differs from the one specified in the configuration file. The message gives the installed type and the configured type.

What to check

  • Compare the two types shown in the message.
  • If a drive unit has just been replaced, check that the part number is identical to the original or update the configuration.
  • Do not operate with a non-conforming drive unit type: the configured current limits would not match the hardware.
  • Note: Read together with 39418 (unknown drive unit type) and 34313 (Drive Module Key): three variants of the same hardware/configuration consistency check.
