Position control under vector control and PM sensorless vector control
Parameters
5 - 172
If it is set under PM sensorless vector control, Home position return parameter setting error (HP3)
occurs.
6
Count type front end
reference
Deceleration starts at the front end of the proximity dog, and the position is shifted by the post-
dog travel distance and home position shift distance. The position after the shifts is set as the
home position.
Set pulses required for changing the speed from the home position speed to the creep speed or
more as the total of the post-dog travel distance and home position shift amount.

NOTE
Home position return automatic back-off function
In a system that uses home position return with proximity dog, if the home position return is com-
manded while the motor is in a position within the proximity dog, the motor moves out of the
proximity dog once, then starts deceleration to stop when it comes to the proximity dog again.
The home position return is performed automatically after that.
