2.2 List of parameters
Description: Sets the dead time to symmetrize the speed setpoint for active torque pre-control.
The selected multiplier refers to the sampling time of the speed controller (dead time= p1428 * p0115[1]).
Dependency: In conjunction with p1429, this parameter can emulate the characteristics of how the torque is established (dynamic
response of closed current control loop).
The parameter is only effective if the acceleration model is supplied using external acceleration signals (p1400.2 =
1). For p1400.2 = 0, a fixed dead time is used.
Refer to: p1429, p1511
Description: Sets the time constant (PT1) for symmetrizing the speed setpoint for active torque pre-control.
Dependency: In conjunction with p1428, this parameter can emulate the characteristics of how torque is established (dynamic
response of the closed current control loop).
For VECTOR (r0107) the following applies:
The parameter is only effective if the acceleration model is supplied using external acceleration signals (p1400.2 =
1). For p1400.2 = 0, time constant p1442 (or p1452 for sensorless vector control) is used.
Refer to: p1428, p1511
Description: Displays the speed setpoint for pre-controlling the motor model with sensorless vector control.
Note: With p1400.15 = 0 or encoderless torque control, the pre-control signal is kept continuously in the range of the
voltage model.
Description: Sets the natural frequency of a PT2 element for the reference model of the speed controller.
Recommendation: The reference model is correctly set when the characteristics of p1439 (reference model output) and p1445 (actual
speed value) are virtually identical when the I component of the speed controller is disabled.
