310752 Axis %1 drive %2 integral gain for speed controller invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The integral gain in MD 5409: SPEEDCTRL_INTEGRATOR_TIME cannot be repre-
sented.
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: Modify MD 5409: SPEEDCTRL_INTEGRATOR_TIME.
Program Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
310753 Axis %1 drive %2 D component for speed controller invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The D component of the speed controller is too high:
• Modify MD 5431: SPEEDCTRL_DIFF_TIME_A (gain on A-side of cylinder edge)
• or MD 5432: SPEEDCTRL_DIFF_TIME (gain for piston adjustment with lowest natural
frequency)
• or MD 5433: SPEEDCTRL_DIFF_TIME_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 D component of the speed controller:
• Modify MD 5431: SPEEDCTRL_DIFF_TIME_A (gain on A-side of cylinder edge)
• or MD 5432: SPEEDCTRL_DIFF_TIME (gain for piston adjustment with lowest natural
frequency)
• or MD 5433: SPEEDCTRL_DIFF_TIME_B (gain on B-side of cylinder edge)
Program Con-
tinuation:
Clear alarm with the RESET key in all channels. Restart part program.
310754 Axis %1 drive %2 friction compensation gradient too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Reduce the friction compensation gradient component MD 5460:
FRICTION_COMP_GRADIENT is too high.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
