Remedy:
Program Continuation:
Axis %1 drive %2 voltage/frequency mode: converter frequency invalid
%1 = NC axis number %2 = Drive number
Only converter frequencies (MD 1100: $MD_PWM_FREQUENCY (pulse width modulation frequency)) of 4 kHz or 8 kHz are permissible in V/f mode (selected via MD 1014: $MD_UF_MODE_ENABLE).
- 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.
Please inform the authorized personnel/service department. Check and, if necessary, correct the torque adaptation factor MD 1100: $MD_PWM_FREQUENCY (pulse width modulation frequency) or remedy the problem by deselecting V/f mode MD 1014: $MD_UF_MODE_ENABLE.
Switch control OFF - ON.
