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. For sensorless vector control (p1300 = 20) the reference model is
disabled in open-loop speed controlled operation (refer to p1755).
Refer to: p1434, p1435
Description: Sets the damping 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.
Dependency: In conjunction with p1433 and p1435, the characteristics (in time) of the P-controlled speed control loop can be
emulated.
For VECTOR (r0107) the following applies:
The reference model is activated with p1400.3 = 1.
Refer to: p1433, p1435
Description: Sets the "fractional" dead time for the reference model of the speed controller.
This parameter emulates the computing dead time of the proportionally controlled speed control loop.
The selected multiplier refers to the speed controller clock cycle (dead time= p1435 * p0115[1]).
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.
Dependency: In conjunction with p1433 and p1434, the characteristics (in time) of the P-controlled speed control loop can be
emulated.
For VECTOR (r0107) the following applies:
The reference model is activated with p1400.3 = 1.
Refer to: p0115, p1433, p1434
Description: Display and connector output for the speed setpoint at the output of the reference model.
Dependency: For VECTOR (r0107) the following applies:
The reference model is activated with p1400.3 = 1.
