[2522.7] r1407.7
<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 to the actual value 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. 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 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> For SERVO, the following applies: Only when the function module "extended setpoint channel" is activated (r0108.8 = 1).
<6> The value is displayed correctly only with r0899.2 = 1 (Operation enabled).
