Parameters
List of Parameters
p2160[0...n] Delay for n_act comparison with speed threshold value 6 / Del compar n_6
Access level: 3
Can be changed: U, T
Units group: -
Min
0 [ms]
Description: Sets the delay time for the comparison of the speed with the speed threshold value 6 (p2159).
Dependency: Refer to: p2150, p2159
p2161[0...n] Speed threshold 3 / n_thresh val 3
Access level: 3
Can be changed: U, T
Units group: 3_1
Min
0.00 [rpm]
Description: Sets the speed threshold value for the signal "|n_act| < speed threshold value 3" (BO: r2199.0).
Dependency: Refer to: p2150, r2199
p2162[0...n] Hysteresis speed n_act > n_max / Hyst n_act>n_max
Access level: 3
Can be changed: U, T
Units group: 3_1
Min
0.00 [rpm]
Description: Sets the hysteresis speed (bandwidth) for the signal "n_act > n_max" (BO: r2197.6).
Dependency: Refer to: r1084, r1087, r2197
Notice: For p0322 = 0, the following applies: p2162 <= 0.1 * p0311
For p0322 > 0, the following applies: p2162 <= 1.02 * p0322 - p1082
If one of the conditions is violated, p2162 is appropriately and automatically reduced when exiting the commission-
ing mode.
Note: For a negative speed limit (r1087) the hysteresis is effective below the limit value and for a positive speed limit
(r1084) above the limit value.
If significant overshoot occurs in the maximum speed range (e.g. due to load shedding), you are advised to
increase the dynamic response of the speed controller (if possible). If this is insufficient, the hysteresis p2162 can
only be increased by more than 10% of the rated speed when the maximum speed (p0322) of the motor is suffi-
ciently greater than the speed limit p1082.
p2163[0...n] Speed threshold 4 / n_thresh val 4
Access level: 3
Can be changed: U, T
Units group: 3_1
Min
0.00 [rpm]
Description: Sets the speed threshold value for the "speed setpoint - actual value deviation in tolerance t_off" signal/message
(BO: r2197.7).
Dependency: Refer to: p2164, p2166, r2197
