2 Parameters
2.2 List of parameters
A higher value results in a higher degree of ruggedness when reversing at low speeds, as well as in the field
weakening 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
Caution: The safety functionality is only completely guaranteed after this time has expired.
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
If this value is reduced, this can have a negative impact on the actual value acquisition and plausibility check – and
result in Safety message C30711 with the message value 1041 or 1042.
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
The set time is rounded internally to an integer multiple of the monitoring clock cycle.
Description: Sets the filter time for smoothing the actual value with sensorless actual value sensing.
Notice: This parameter is overwritten by the copy function of the safety functions integrated in the drive.
A longer filter time results in a longer response time.
Description: Sets the minimum current for encoderless actual value sensing referred to 1 A (i.e. 1 % = 10 mA).
- the value must be increased if C30711 has occurred with message value 1042.
- the value must be decreased if C30711 has occurred with message value 1041.
