The Motor starts in CCW* direction, decelerates and stops when it enters the HLS range (
2
Home position proximity), and then reverses its direction (
3
). The Motor goes out the HLS
range once, then reverses again and enters the HLS range with the Home position Near-Zero
velocity (
4
). It moves to the point at where the position sensor value becomes 0 for the first
time (= rising edge of the øZ), and thus completes the 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 specified this time, the Motor moves further for the offset value
from the 0 point of the position sensor, then completes Home Return operation.
l
The Home Return can be also executed with the following ways.
à
Select t a channel where the HS command is set, and then input the RUN command.
à
Execute the HS command through the RS-232C communication.
l
The Home Return sequence differs by the starting point of Home Return as shown in Figure 6-4.
