Axis %1 drive %2 D component for speed controller invalid
%1 = NC axis number
%2 = Drive number
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)

• 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)
Clear alarm with the RESET key in all channels. Restart part program.
