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
the 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
generator down
the ramp-function generator down ramp (p1121).
ramp followed by
• When zero speed is detected, the motor holding brake (if
pulse inhibit
parameters have been assigned for it) is closed (p1215).
The pulses are suppressed when the brake closing 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.
Closed-loop torque control (p1300 = 23)
• The following applies to closed-loop torque control
mode:
Reaction as for OFF2
• When the system switches to closed-loop control with
p1501, the following applies:
No separate braking reaction.
If the actual speed value drops below the speed thresh-
old (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 closing time
(p1217) expires.
As for OFF1, but Faults with this fault reaction do not become effective until
delayed after the delay time set in p3136.
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.
