<1> 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.
<2> For OFF1/OFF3, the ramp-function generator ramp is active. The ramp-function generator is set (SERVO: to the
actual value, VECTOR, VECTOR3P, VECTORGL, VECTORMV, VECTORSL: 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.
For SERVO is valid: When the function module "extended setpoint channel" is not active (r0108.8 = 0), for
OFF1/OFF3 the down ramp of the basic ramp-function generator is effective (refer to n_set_4 on [3060.8]).
<3> The interpolator is only active with activated "basic positioner" Function Module or with isochronous PROFIdrive
mode and sign of life received by the master (STW2.12 ... STW2.15).
<4> 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 speed 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").
<5> The value is displayed correctly only with r0899.2 = 1 (Operation enabled).
<6> For SERVO only.
<7> For VECTOR, VECTOR3P, VECTORMV only.
<8> For VECTORGL only.
<101> To view the pre-assignment of the sampling times in p0115, refer to p0112.
