Description: Sets the monitoring time to define the brake ramp.
The rate of rise of the brake ramp depends upon p9381 (reference value) and p9383 (monitoring time).
Dependency: Refer to: p9381, p9382
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Description: Sets the tolerance of the plausibility monitoring of the current and voltage angle.
A higher value results in a higher degree of ruggedness when reversing at low speeds, as well as in the field weak-
ening range for load steps.
An increase is advantageous, if the current or voltage at the motor become small.
Dependency: Refer to: p9507
Refer to: F30681, C30711
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
Reducing this value can adversely affect the actual value sensing and the plausibility check.
When the value is increased, this results in a longer evaluation delay and a higher velocity deviation (r9787).
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
For synchronous motors, the value 4 must be set.
If value = -1:
- for synchronous motors, the calculation is automatically made with the value 4.
- for induction motors, the calculation is automatically made with a value of 0 (if the code number of the power unit
p0201[0] < 14000, otherwise with a value of 2).
Description: Sets the delay time to evaluate the encoderless actual value sensing after the pulses have been enabled.
The value must be greater than or equal to the motor magnetizing time (p0346).
Dependency: Refer to: C30711
