Axis %1, drive %2 distance-coded scale is set incorrectly
%1 = NC axis number
%2 = drive number
When a distance-coded scale (MD 5011 bit 7=1) is selected, a linear measuring
system must also be configured (MD 5011 bit 4=1).
Mode group not ready.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
Alarm display.
Interface signals are set.
MD 5011: ACTUAL_VALUE_CONFIG (configuration of actual-value sensing)
and configure if necessary.
Switch control system OFF and ON again.
Axis %1, drive %2 feedforward control gain too high
%1 = NC axis number
%2 = drive number
The feedforward control gain is calculated from the reciprocal of the controlled
system gain in drive MD 5435: CONTROLLED_SYSTEM_GAIN.
NC not ready.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
S
Increase the speed controller cycle time in MD 5001:
SPEEDCTRL_CYCLE_TIME.
S
Reduce the force controller feedforward factor in MD 5247:
FORCE_FFW_WEIGHT.
S
Increase the controlled system gain setting in MD 5435: CON-
TROLLED_SYSTEM_GAIN.
Cancel alarm in all channels by pressing RESET. Restart part program.
Axis %1, drive %2 proportional gain of velocity controller too high
%1 = NC axis number
%2 = drive number
The P gain for the velocity controller is too high:
S
MD 5406: SPEEDCTRL_GAIN_A (gain at cylinder edge A end)
Or
S
MD 5407: SPEEDCTRL_GAIN (gain for piston position with lowest natural
frequency)
Or
S
MD 5408: SPEEDCTRL_GAIN_B (gain at cylinder edge B end)
