5. OPERATION
2) Forward rotation start coordinate system selection (parameter No.1)
Choose the servo motor rotation direction at the time when the forward rotation start (RYn1) is
switched on.
Parameter No. 1 setting
3) Feed length multiplication selection (parameter No.1) Set the unit multiplication factor (STM) of
position data. The actual moving distance is the result of multiplying the entered position data
by the unit multiplication factor.
