Description: Sets the hysteresis for the changeover speed of the motor model for sensorless operation.
Dependency: Refer to: p1755
Note: The parameter value refers to p1755.
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 sensorless 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.
Description: Sets the minimum time for falling below the changeover speed when changing from closed-loop controlled opera-
tion to open-loop controlled operation.
Dependency: Refer to: p1755, p1756
Description: Sets the minimum time for exceeding the changeover speed when changing from open-loop controlled operation to
closed-loop controlled operation.
Dependency: Refer to: p1755, p1756
