4 Faults and alarms
4.1 Overview of faults and alarms
Fault reactions
The following fault reactions are defined:
Note
The following table lists all fault reactions and their meanings used for the entire SINAMICS
drive family.
Table 4-2 Fault reactions
List PROFIdrive Reaction Description
NONE - 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.
OFF1 ON/
OFF Brake along the
ramp-function
generator down
ramp followed by
pulse inhibit Closed-loop speed control (p1300 = 20, 21)
• n_set = 0 is input immediately to brake the drive along the ramp-
function generator ramp down (p1121).
•
When zero speed is detected, the motor holding brake (if
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.
OFF1_
DELAYED - As for OFF1,
however delayed Faults with this fault reaction only become effective after the delay
time in p3136 has expired.
The remaining time up to OFF1 is displayed in r3137.
OFF2 COAST
STOP Internal/external
pulse inhibit Closed-loop speed and torque control
•
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.
