Alarm 300712

Siemens 300712 - Axis drive configuration of controller structure (higher dynamic

On a 2-axis module, an attempt was made to change the control structure via MD 1004: $MD_CTRL_CONFIG in such a way that speed control would be performed in advance of current control. This is only allowed on 1-axis modules in order to improve the dynamic response! 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

  • On a 2-axis module, an attempt was made to change the control structure via MD 1004: $MD_CTRL_CONFIG in such a way that speed control would be performed in advance of current control.
  • This is only allowed on 1-axis modules in order to improve the dynamic response!

Troubleshooting Steps

  1. 1Please inform the authorized personnel/service department.
  2. 2In the drive MD 1004: $MD_CTRL_CONFIG bit 2 must be set to zero (no) (default setting).
  3. 3This ensures that the current control acts before the speed control.
  4. 4Switch control OFF - ON
