i950: EtherCAT fieldbus: Partial error message when switching from INIT to OPERATIONAL state (fixed as of V01.09.01)

Removed from:
Servo-Inverter i950 FW:    from V01.09.01
 
Behavior of the new version:
The EtherCAT state 'Operational' is now reliably reached even after multiple state changes via INIT.
Description of behavior:
In case of multiple EtherCAT-state changes from  OP -> INIT -> OP, the i950 sporadically remains in the ERR SAFEOP state with AL status code 0x001b (Sync Manager watchdog).
Bit 0 (watchdog elapsed) is set in parameter 0x2369:000 (EtherCAT error).
The described behavior was observed in the field.

Under which conditionsdoes the behavior occur?

  • EtherCAT communication via the EtherCAT network option
  • multiple EtherCAT-State change from  OP -> INIT -> OP

Affected products:
Servo Inverter i950 FW

Short-term measures / Assessment / Recommendations:

To remedy this, repeat the state change INIT -> OP.
