Alarm 310702

Siemens 310702 - Axis drive position controller cycle time invalid

The monitor in the 611D module has detected a position controller pulse rate which is beyond the permissible limits. The conditions for a permissible position controller pulse rate are: 1. Minimum cycle time: 250µs 2. Maximum pulse rate: 4 s 3. The position controller pulse rate must be a multiple of the speed controller cycle given in the drive MD 5001: SPEEDCTRL_CYCLE_TIME Control reaction: NC not ready. The NC switches to follow-up mode. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm.

Safety

  • Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.

Common Causes

  • The monitor in the 611D module has detected a position controller pulse rate which is beyond the permissible limits.
  • The conditions for a permissible position controller pulse rate are: 1.
  • Minimum cycle time: 250µs 2.

Troubleshooting Steps

  1. 1Change the position controller pulse rate on the NC.
  2. 2Switch control OFF - ON
