Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 format error
%1 = NC axis number
%2 = Drive number
The calculated filter coefficients of a bandstop filter are beyond the range of the internal
format.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- NC not ready.
- Channel not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.

Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 asynchronous mode: converter frequency invalid
%1 = NC axis number
%2 = Drive number
Only a converter frequency of 4 kHz or 8 kHz is permitted in asynchronous mode
(selected by MD 1465 < MD 1146).
• Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)
• Modify MD 1146: $MD_MOTOR_MAX_ALLOWED_SPEED (maximum motor speed)
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- NC not ready.

- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.

- Interface signals are set.
Please inform the authorized personnel/service department. Modify MD 1100:
$MD_PWM_FREQUENCY (pulse width modulation frequency) or deselect AM mode
(make the value in MD 1465: $MD_SWITCH_SPEED_MSD_AM less than the value in
MD 1146: $MD_MOTOR_MAX_ALLOWED_SPEED.
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 asynchronous mode: speed control gain too high
%1 = NC axis number
%2 = Drive number
The value in MD 1451: $MD_SPEEDCTRL_GAIN_1_AM (proportional gain of AM speed
controller) is too high.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
