Parameters
Parameter list
Dependency:
In conjunction with p1429, this parameter can simulate the characteristics of how the torque is established (dynamic
response of 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, a fixed deadtime is used.
Refer to: p1429, p1511
p1429[0...n]
Speed pre-control balancing time constant / n_prectrl bal T
VECTOR (n/M)
Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0.00 [ms]
Description:
Sets the time constant (PT1) for balancing the speed/velocity setpoint for the active torque/force pre-control.
Dependency:
In conjunction with p1428, this parameter can simulate 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 closed-loop vector control) is used.
Refer to: p1428, p1511
p1433[0...n]
Speed controller reference model natural frequency / n_ctrl RefMod fn
VECTOR (n/M)
Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0.0 [Hz]
Description:
Sets the natural frequency of a PT2 element for the reference model of the speed/velocity controller.
Recommenda-
The reference model is correctly set when the characteristics of p1429 (reference model output) and p1445 (actual
tion:
speed value) are virtually identical when the I-component of the speed controller is disabled.
Dependency:
Together with p1434 and p1435, the characteristics (in the time domain) of the closed-loop speed control (P) can be
emulated.
For VECTOR (r0107) the following applies:
The reference model is activated with p1400.3 = 1.
Refer to: p1434, p1435
p1434[0...n]
Speed controller reference model damping / n_ctrl RefMod D
VECTOR (n/M)
Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0.000
Description:
Sets the damping of a PT2 element for the reference model of the speed/velocity controller.
Recommenda-
The reference model is correctly set when the characteristics of p1429 (reference model output) and p1445 (actual
tion:
speed value) are virtually identical when the I-component of the speed controller is disabled.
Dependency:
In conjunction with p1433 and p1435, the characteristics (in time) of the P-controlled speed control loop can be sim-
ulated.
For VECTOR (r0107) the following applies:
The reference model is activated with p1400.3 = 1.
Refer to: p1433, p1435
