For manufacturer setting
500 PT05 Home position return speed
Set a servo motor speed at home position return.
Setting range: 0 to permissible instantaneous speed
10 PT06 Creep speed
Set a creep speed after proximity dog at home position
return.
Setting range: 0 to permissible instantaneous speed
0 PT07 Home position shift distance
Set a shift distance from the Z-phase pulse detection
position in the encoder.
Setting range: 0 to 65535
0 PT08 Home position return position data
Set a current position at home position return
completion.
Additionally, when the following parameters are
changed, the home position return position data will be
changed. Execute the home position return again.
"Position data unit" in [Pr. PT01]
"Feed length multiplication (STM)" in [Pr. PT03]
"Home position return type" in [Pr. PT04]

Set a travel distance after proximity dog at home position
return for the count type, dog type rear end reference,
count type front end reference, and dog type front end
reference.
Setting range: 0 to 65535
