IndraDrive HCS01 – F2087 Module Group Communication Error. Non-resettable

Hi everyone,

I'm dealing with a persistent F2087 – Module group communication error on a single IndraDrive unit and I'm hoping someone has seen this before.

Drive details:

  • Drive: HCS01.1E-W0018-A-03-B-ET-EC-NN-NN-NN-FW

  • Firmware: FWA-INDRV*-MPB-20V32-D5-1-NNN-NN

  • Communication: EtherCAT, connected to a ctrlX CORE

What happened:
The drive ran fine for a period, then the F2087 fault started appearing sporadically. Over time it became constant and non-resettable — even after restarting the EtherCAT bus, the ctrlX CORE, and the drive itself.

What we've already checked:

  • EMC, grounding, and cabling have all been verified

  • A second identical machine (same setup, FW MPB-20V26) runs without any issues

  • The fault is isolated to this one drive

  • The drive was swapped with a replacement unit — the fault did NOT follow the drive, meaning the replacement drive runs without issues in the same position

This points away from a pure hardware defect on the original drive and suggests something in the setup, configuration, or firmware may be the cause.

Has anyone experienced F2087 becoming non-resettable like this, and if so, what was the root cause?

Thanks in advance!
