Siemens 301708 - Axis drive actual value synchronisation not allowed

The actual value synchronization for drift/slippage in MD 1301: $MD_SAFE_FUNCTION_ENABLE (safe functions enable) is deselected. This is only allowed with SBH/SG monitoring, since the absolute actual position is irrelevant for this type of monitoring. However, safe end position and/or cam monitoring is also selected Control reaction: Mode group not ready. Channel not ready. NC Start disable in this channel. Interface signals are set.

This is only allowed with SBH/SG monitoring, since the absolute actual position is irrelevant for this type of monitoring. However, safe end position and/or cam monitoring is also selected Control reaction: Mode group not ready. 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 actual value synchronization for drift/slippage in MD 1301: $MD_SAFE_FUNCTION_ENABLE (safe functions enable) is deselected.
  • This is only allowed with SBH/SG monitoring, since the absolute actual position is irrelevant for this type of monitoring.
  • However, safe end position and/or cam monitoring is also selected

Troubleshooting Steps

  1. 1Please inform the authorized personnel/service department.
  2. 2Deselect actual value synchronization for drift/slippage or the safe end position and/or safe cam monitoring in MD 1301: $MD_SAFE_FUNCTION_ENABLE (safe functions enable).
  3. 3Switch control OFF - ON
