MD 5431: SPEEDCTRL_DIFF_TIME_A (gain at cylinder edge A end) or
S
MD 5432: SPEEDCTRL_DIFF_TIME (gain for piston position with lowest
natural frequency) or
S
MD 5433: SPEEDCTRL_DIFF_TIME_B (gain at cylinder edge B end)
Cancel alarm in all channels by pressing RESET. Restart part program.

%1 = NC axis number
%2 = drive number
Reduce the friction compensation gradient component MD 5460:
FRICTION_COMP_GRADIENT is too high.
