SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Axis %1, drive %2 distance-coded scale is incorrectly parameterized
%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).
NC not ready
Channel not ready.
NC Stop in response to alarm.
NC Start disable.
Alarm is displayed.
Interface signals are set.
Check 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
Switchover for entire channel via MD might be possible.
Channel not ready.
NC Stop in response to alarm.
NC Start disable.
The NC switches to follow-up mode.
Alarm is displayed.
Interface signals are set.
S
Increase the velocity controller cycle in MD 5001:
SPEEDCTRL_CYCLE_TIME.
S
Reduce the feedforward control factor of the force controller 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 key. Restart the 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)
