Remedy:
Program Continuation:
Axis %1 drive %2 encoder cut-off frequency exceeded
%1 = NC axis number %2 = Drive number
Actual speed value exceeds encoder limit frequency fg,max = 650kHz; fg = nist * MD 1005
- Mode group 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.
- Channel not ready.
Please inform the authorized personnel/service department.
The wrong encoder may be in use.
Correct MD 1005: Does the number of encoder lines match the setting in MD 1005 $MD_ENC_RESOL_MOTOR (encoder resolution for motor measuring system)?
Is the motor encoder cable connected correctly?
Is the motor encoder cable shield installed flat?
Replace the motor (the encoder is defective).
Check the encoder, encoder cable and shield connection for loose contact or cable breakage.
Replace the encoder.
Replace the 611D control module.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
