Related parameters
(1) Rotation direction selection
Table8.16.5.2
Parameter Description Effective Category
Pt000
CCW is the forward direction.
After power on Setup
t.1 CW is the forward direction. (reverse mode)
(2) Usage of external encoder
Table8.16.5.3
Parameter Description Effective Category
Pt002
Do not use external encoder.
After power on Setup
t.1
The external encoder moves in forward direction for motor
CCW rotation.
t.2 Reserved (Do not modify.)
t.3
The external encoder moves in reverse direction for motor
CCW rotation.
t.4 Reserved (Do not modify.)
8.16.6 Related settings of unit conversion
Set the feed value (screw lead) of external encoder (optical scale) for one motor revolution by Pt20A. Set
linear unit length (resolution) of external encoder by Pt20B. If reduction gearbox is used, set gear ratio at
motor side (full-closed loop) by Pt20C and gear ratio at load side (full-closed loop) by Pt20D.
