Setting method

Setting with servo parameters
■Degree unit selection
Set the unit to "degree" with [Pr. PT01.2 Unit for position data].
Page 101 Position command unit selection function
■Degree unit rotation direction selection
Use [Pr. PT03.2 Degree unit rotation direction selection] to set the rotation direction for when the unit is set to "degree".
Servo parameter Symbol
PT03.2 *FTY
Setting with object dictionary
Use [Positioning option code (Obj. 60F2h)] to set the rotation direction for when the unit is set to "degree". Change the setting
while the servo motor is stopped (Target reached is on). If the setting is changed while the servo motor is rotating (Target
reached is off), the new setting value will be reflected at a positioning start (bit 4 of Controlword is on) after Target reached is
turned on.
For details on the objects, refer to the User's Manual (Object Dictionary).

0 Rotates to the target position in the direction specified with the sign of the position data.
2 Rotates in the address decreasing direction regardless of the sign of the position data.
3 Rotates in the address increasing direction regardless of the sign of the position data.
1 Rotates in the direction with the shorter distance from the current position to the target position. If the
distance from the current position to the target position is the same in the CCW and CW directions, the
servo motor rotates in the CCW direction.
