Alarm 301703

Siemens 301703 - Axis drive encoder/motor type are not compatible

If a linear motor was selected (motor selection menu), but no linear scale was configured (MD 1011.4=0), or if a rotary motor was selected, but a linear scale configured (MD 1011.4=1), then this error is triggered. Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration IM) Control reaction: Mode group not ready. Channel not ready. NC Start disable in this channel. Interface signals are set.

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

  • If a linear motor was selected (motor selection menu), but no linear scale was configured (MD 1011.4=0), or if a rotary motor was selected, but a linear scale configured (MD 1011.4=1), then this error is triggered.
  • Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration IM)

Troubleshooting Steps

  1. 1Please inform the authorized personnel/service department.
  2. 2Encoder type must be parameterized according to the motor type.
  3. 3Switch control OFF - ON
