List of parameters
p9581 SI Motion brake ramp reference value (processor 1) / SI Mtn ramp ref P1
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_DP_F
Units group: -
CU250D-2_PN_F
Min
600.0000 [rpm]
Description: Sets the reference value 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: p9582, p9583
p9582 SI Motion brake ramp delay time (processor 1) / SI Mtn ramp t P1
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_DP_F
Units group: -
CU250D-2_PN_F
Min
10.00 [ms]
Description: Sets the delay time for monitoring the brake ramp.
Monitoring of the brake ramp starts once the delay time has elapsed.
Dependency: Refer to: p9581, p9583
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_DP_F
Units group: -
CU250D-2_PN_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
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_DP_F
Units group: -
CU250D-2_PN_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 weak-
ening 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.
