p9581 SI Motion brake ramp reference value (processor 1) / SI Mtn ramp ref P1
CU240E-2_F Access level: 3
CU240E-2_PN_F
Can be changed: C(95)
CU240E-2_DP_F
Unit group: -
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

CU240E-2_PN_F
10.00 [ms]
CU240E-2_DP_F
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
Note: The set time is rounded internally to an integer multiple of the monitoring clock cycle.
Internally, the set time is limited downwards to 2 safety monitoring clock cycles (2 * 12 ms).
p9583 SI Motion brake ramp monitoring time (processor 1) / SI Mtn rp t_mon P1

CU240E-2_DP_F
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

CU240E-2_DP_F
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).
