Emergency stop did not finish within the expected time.
Check:
− The settings of 31.31 Emergency ramp supervision and
31.32 Emergency ramp supervision delay.
− The settings of parameters 23.11 ... 23.19 for Off3 stop
mode 1 (21.03 Emergency stop mode = Ramp stop).
− The setting of 23.23 Emergency stop time for Off3 stop
mode 2 (21.03 Emergency stop mode = Emergency ramp
stop).
− The current and torque limits in group 30 Control limits.
