2.2 List of parameters
p9583 SI Motion brake ramp monitoring time (processor 1) / SI Mtn rp t_mon P1
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_PN_F
Unit group: -
CU250D-2_DP_F
Min
0.50 [s]
Description: Sets the monitoring time to define the brake ramp.
The rate of rise of the brake ramp depends upon p9581 (reference value) and p9583 (monitoring time).
Dependency: Refer to: p9581, p9582
Note: The set time is rounded internally to an integer multiple of the monitoring clock cycle.
p9585 SI Motion actual value sensing sensorless fault tolerance (CU) / ActVal sl tol CU
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_PN_F
Unit group: -
CU250D-2_DP_F
Min
-1
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
weakening range for load steps.
An increase is advantageous, if the current or voltage at the motor become small.
Dependency: Refer to: r9787
Refer to: F01681, C01711
Notice: 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).
p9586 SI Motion actual value sensing sensorless delay time (P1) / ActVal sl t_del P1
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_PN_F
Unit group: -
CU250D-2_DP_F
Min
5.00 [ms]
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: C01711
Caution: The safety functionality is only completely guaranteed after this time has expired.
Notice: If this value is reduced, this can have a negative impact on the actual value acquisition and plausibility check – and
result in Safety message C01711 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.
