6.5.3.1 Fail Safe Torque
Parameters
: Torque
Function
:
Supervises the fail-safe limits for Torque, The fail safe limits are active also during the
step overshoot time.
The absolute value of the measured torque must be lower than the fail-safe torque limit
during the entire step, including the post step check time. Note! The torque restriction is
supervised also during the Torque Spike Elimination phase.

Trace
:
Torque is shown as a horizontal line from step start to step stop in trace when Torque vs.
Time is selected. Fail safe limits parameters must be enabled in the trace form (see
View of trace curves).
