p1756 Motor model changeover speed hysteresis encoderless operation / MotMod n_chgov hys
Access level: 3 Calculated: CALC_MOD_REG Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: 6730, 6731
Min:
0.0 [%]
Max:
95.0 [%]
Factory setting:
50.0 [%]
Description: Sets the hysteresis for the changeover speed of the motor model for encoderless operation.
Dependency: See also: p1755
Note
The parameter value refers to p1755.
Extremely small hystereses can have a negative impact on the stability in the changeover speed range, and very high
hystereses in the standstill range.
p1780[0...n] Motor model adaptation configuration / MotMod adapt conf
CUG120XA_USS
(PM330)
Access level: 3 Calculated: CALC_MOD_CON Data type: Unsigned16
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:

Max:

Factory setting:
0000 1000 0001 0100 bin
Description: Sets the configuration for the adaptation circuit of the motor model.
Induction motor (ASM):
Rs, Lh and offset compensation.
Bit field: Bit Signal name 1 signal 0 signal FP
01 Select motor model ASM Rs adaptation Yes No -
02 Select motor model ASM Lh adaptation Yes No -
04 Select motor model offset adaptation Yes No -
07 Select T(valve) with Rs adaptation Yes No -
10 Filter time combination current like current ctrl integral time Yes No -
11 Fast flying restart with voltage model for induction motor Yes No -
Dependency: In the U/f characteristic operating mode, only bit 7 and bit 11 are relevant.
For active motor model feedback (see p1784), the Lh adaptation is internally deactivated automatically.
Note
When selecting the compensation of the valve interlocking via Rs (bit 7), the compensation in the gating unit is
deactivated and is instead taken into account in the motor model.
In order that the correction values of the Rs and Lh adaptation (selected using bit 0 ... bit 1) are correctly accepted when
changing over the drive data set, a dedicated motor number must be entered into p0826 for each different motor.
ASM: Induction motor
RESM: synchronous reluctance motor
p1800[0...n] Pulse frequency setpoint / Pulse freq setp
Access level: 2 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 8021
Min:
0.500 [kHz]
Max:
16.000 [kHz]
Factory setting:
4.000 [kHz]
Description: Sets the pulse frequency for the converter.
This parameter is pre-set to the rated converter value when the drive is first commissioned.
Dependency: Minimum pulse frequency: p1800 >= 12 * p1082 * r0313 / 60
