Overview of Alarms
SIMODRIVE alarms
310756 Axis %1 drive %2 controlled system gain is less than or equal to zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The controlled system gain in drive MD 5435: CONTROLLED_SYSTEM_GAIN is less than or equal
to zero.
Reaction: 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 valid controlled system gain in drive MD 5435: CONTROLLED_SYSTEM_GAIN (see model
data calculations).
Program Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
310757 Axis %1 drive %2 blocking frequency > Shannon frequency
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The blocking frequency of a speed setpoint filter or manipulated variable filter is greater than the
Shannon sampling frequency from the sampling theorem.
Reaction: 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: - The blocking frequency in drive MD 5514: SPEED_FILTER_1_SUPPR_FREQ
- or in drive MD 5210: OUTPUT_VCTRL_FIL_1_SUP_FREQ
- or in drive MD 5213: OUTPUT_VCTRL_FIL_2_SUP_FREQ
- or in drive MD 5268: FFW_FCTRL_FIL_1_SUP_FREQ
- or in drive MD 5288: OUTPUT_FIL_1_SUP_FREQ must be less than the reciprocal value of two
speed controller cycle times MD 5001: SPEEDCTRL_CYCLE_TIME, i.e. less than 1 / (2 * MD 5001 *
31.25 microsec).
Program Clear alarm with the RESET key in all channels. Restart part program.
