p1756 Motor model changeover speed hysteresis encoderless operation /
MotMod n_chgov hys
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.0 [%]
Description: Sets the hysteresis for the changeover speed of the motor model for encoderless operation.
In the case of separately excited synchronous motors, the lower hysteresis value is calculated with p1756 * p1755; in
the case of all other types of motor, p1755 * (1 - p1756) is used.
Dependency: In U/f characteristic mode the parameter is of no significance.
Refer to: p1755
Note: The parameter value refers to p1755.
In the case of separately excited synchronous motors, the lower hysteresis value is calculated with p1755 * p1756; in
the case of all other types of motor, p1755 * (1 - p1756) is used.
p1757[0...n] Motor model w/o enc. op./cl.-loop controlled stab. controller Kp / MotMod w/o enc Kp
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: SESM, REL
Min
0.01
Description: Sets the gain of the transient response controller when the motor model changes over from open-loop controlled
operation to closed-loop controlled operation.
Note: Only for ASM and PSM in encoderless operation:
The settling range starts at 0.5 * p1755 * p1756.
For ASM it ends at p1755 * p1756 or at p1755, if p1759 is at the maximum value.
For PSM it always ends at p1755 * p1756.
p1758[0...n] Motor model changeover delay time closed/open-loop control / MotMod t cl_op
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PMSM, SESM, REL
Min
100 [ms]
Description: Sets the minimum time for falling below the changeover speed when changing from closed-loop controlled operation
to open-loop controlled operation.
Dependency: The wait time has no significance if the setpoint speed before the ramp-function generator lies in the open-loop
speed controlled operating range. In this case, the change is made without any delay.
Refer to: p1755, p1756
Note: If p1758 is changed, commissioning must be selected in order to validate the value for the blocking monitoring.
