<1> For p1145 > 0, the 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 using p1145.
<2> For OFF1/OFF3 the ramp-function generator ramp is active. The ramp-function generator is
set (SERVO: to the actual value, VECTOR 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 being 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. When the function module "extended setpoint channel" (r0108.8 = 0) is not active 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 effective for clock-cycle synchronous PROFIBUS operation and sign-
of-life received from 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 distances itself from 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> For SERVO, the following applies: Only when the function module "expanded setpoint channel" is activated (r0108.8 = 1).
<6> The value is only correctly displayed if the drive is enabled.
<101> Pre-assignment of the sampling times in p0115, refer to p0112.
