Fault reactions
The following fault reactions are defined:

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 a change is made into
tracking mode until the fault has been rectified and
acknowledged.
OFF1 ON/
OFF

Closed-loop speed control (p1300 = 20, 21)
• n_set = 0 is input immediately to brake the drive along
the deceleration ramp (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 in p1226 or if the monitoring time (p1227)
started when 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 changing over to closed-loop control using p1501,
the following applies:
There is no dedicated braking response.
If the actual speed drops below the speed threshold
(p1226), or the timer stage (p1227) has expired, the
motor holding brake (if parameterized) is closed. The
pulses are suppressed when the brake application time
(p1217) expires.
OFF2 COAST
STOP
Internal/external
pulse disable
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.
