Fault reactions
Note
The following table lists all fault reactions and their meanings used for the entire SINAMICS
drive family.
The following fault reactions are defined:

Reaction
None No reaction when a fault occurs.
Note
When the "Basic positioner" function module is activated (r0108.4 =
1), the following applies:
When a fault occurs with fault reaction "NONE", an active traversing
task is interrupted and the system switches to tracking mode until the
fault has been rectified and acknowledged.
Brake along the Closed-loop speed control (p1300 = 20, 21)
ramp-function
• n_set = 0 is input immediately to brake the drive along the ramp-
generator down
function generator ramp down (p1121).
ramp followed by
• When zero speed is detected, the motor holding brake (if
pulse inhibit
parameterized) is closed (p1215). The pulses are suppressed when
the brake application time (p1217) expires.
Zero speed is detected if the actual speed drops below the
threshold (p1226) or if the monitoring time (p1227) started when the
speed setpoint <= speed threshold (p1226) has expired.
Torque control (p1300 = 23)
• The following applies for torque control:
Reaction as for OFF2.
• When the system switches to torque control with p1501, the
following applies:
No separate braking reaction.
If the actual speed value drops below the speed threshold (p1226)
or the timer stage (p1227) has expired, the motor holding brake (if
one is being used) is closed. The pulses are suppressed when the
brake application time (p1217) expires.
As for OFF1, Faults with this fault reaction only become effective after the delay
however delayed time in p3136 has expired.
The remaining time up to OFF1 is displayed in r3137.
Internal/external Closed-loop speed and torque control
pulse inhibit
• Instantaneous pulse suppression, the drive "coasts" to a standstill.
• The motor holding brake (if one is being used) is closed
immediately.
• Switching on inhibited is activated.
