Whether to cause the motor to rotate in CW direction or CCW direction when a forward direction pulse is
input can be set using the system parameter for motor rotation direction [SyS-1-06]. Refer to p.55.
Note
When a system parameter has been changed, the new parameter will become effective
after the power is cycled. If a 24 VDC power supply is used, also cycle the 24 VDC power
supply.
