- Alarm display.
- NC Stop on alarm.
Remedy: Check and, if necessary, correct MD 5011: ACTUAL_VALUE_CONFIG (actual value
sensing configuration).
Program Con-
tinuation:
Switch control OFF - ON.
310750 Axis %1 drive %2 feedforward gain too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The feedforward control gain is calculated from the reciprocal of the gain in drive MD
5435: CONTROLLED_SYSTEM_GAIN.
Reactions: - 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.
- Channel not ready.
Remedy: Increase the speed controller cycle time in MD 5001: SPEEDCTRL_CYCLE_TIME.
Reduce the force controller feedforward factor in MD 5247: FORCE_FFW_WEIGHT.
Increase the gain in MD 5435: CONTROLED_SYSTEM_GAIN.
Program Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
310751 Axis %1 drive %2 proportional gain for speed controller too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The P gain of the speed controller is too high:
• Modify MD 5406: SPEEDCTRL_GAIN_A (gain on A-side of cylinder edge)
• or MD 5407: SPEEDCTRL_GAIN (gain for piston adjustment with lowest natural fre-
quency)
• or MD 5408: SPEEDCTRL_GAIN_B (gain on B-side of cylinder edge)
Reactions: - 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.
- Channel not ready.
Remedy: Enter a smaller value for the P gain of the speed controller:
• Modify MD 5406: SPEEDCTRL_GAIN_A (gain on A-side of cylinder edge)
• or MD 5407: SPEEDCTRL_GAIN (gain for piston adjustment with lowest natural fre-
quency)
• or MD 5408: SPEEDCTRL_GAIN_B (gain on B-side of cylinder edge)
Program Con-
