For p1145 > 0, ramp-function generator tracking is activated when the torque limiting
responds. This means that the speed controller output only exceeds the torque limit by a
deviation that can be set via p1145.
For OFF1/OFF3, the ramp-function generator ramp is active. The ramp-function generator is
set to the setpoint (r1170)) and stops the drive with the ramp-downtime (p1121 or p1135).
STW1.4 (enable ramp-function generator) is effective while the drive is stopped via the
ramp-function generator. Depending on the p1115, the basic ramp-function generator [3060]
or the extended ramp-function generator [3070] is effective.
Behavior of the response ramp of the torque limiting:
p1145 = 0.0: No ramp-function generator tracking. The ramp-function generator ramp is no longer in the range of the
frequency actual value.
p1145 = 1.0: The ramp-function generator ramp remains as close as possible to the speed actual value.
p1145 > 1.0: The ramp-function generator ramp is steeper than for p1145 = 1.0 (higher "speed following error").
The value is displayed correctly only with r0899.2 = 1 (operation enabled)
