l Make the Motor Servo-on. (SVON input on)
l Turning the HOS input ON will start Home Return. (
1
)
l The Motor turns in CCW*. When it enters HLS (Home position proximity) area (
2
), it decelerates
and stops momentarily, then reverses its rotational direction. (
3
) The Motor goes out HLS range
once, then reverses again and enters HLS area at the Home position search velocity. (
4
) It moves
to the first point where the resolver value becomes 0 (= rising edge of the øZ) and completes Home
Return.
* The direction of rotation can be changed with the parameter HD (Home Return direction).
HD0 : CW
HD1 : CCW (Shipping set)
l If the Home offset value HO is set, the Motor moves farther past the resolver 0 point by the offset
value, then completes Home Return operation.
l Home Return can be also executed with the following ways.
◊ Select the channel where HS command is set and input RUN command.
◊ Execute HS command through RS-232C communication.
