p1755[0...n] Motor model changeover speed encoderless operation / MotMod n_chgSnsorl
Access level: 3
Can be changed: U, T
Units group: 3_1
Min
0.00 [rpm]
Description: Sets the speed to change over the motor model to encoderless operation.
Dependency: Refer to: p1756
Notice: The changeover speed represents the steady-state minimum speed up to which the motor model can be used
in steady-state operation without encoder.
If the stability is not adequate close to the changeover speed, it may make sense to increase the parameter value.
Note: The changeover speed applies for the changeover between open-loop and closed-loop control mode.
p1756 Motor model changeover speed hysteresis encoderless operation /
MotMod n_chgov hys
Access level: 3
Can be changed: U, T
Units group: -
Min
0.0 [%]
Description: Sets the hysteresis for the changeover speed of the motor model for encoderless operation.
Dependency: Refer to: p1755
Note: The parameter value refers to p1755.
