Reciprocating
• When executing reciprocating run between fixed positions
Slider
• Every time
I
1 is turned on, feed action
→
return action
→
feed action is repeated in turn.
• When power is on, homing operation is executed and
home is set by
I
1.
Coordinate system + direction
depends on configuration of
gear head and machine. When
setting the rotation direction
CCW of motor shaft to +, set
Pr23 at "0", and when setting
CW to +, set Pr23 at "1".

Similarly, after the motor has stopped instantaneously during feed operation, when
I
