This parameter keeps consistency between the direction of rotation of the servomotor and the traveling
direction of the machine.
In case of operation with pulse
The direction of rotation caused upon an input of a forward rotation pulse and high level command
sign or a B-phase pulse lead pulse with A / B phase pulse becomes the forward direction, making
the servomotor rotate forward.
To switch the phase of the output pulse, select the phase of counterclockwise (CCW) rotation of
the servomotor.
In case of operation with speed command voltage
The direction of rotation caused by a positive speed command voltage in a forward command
(FWD) signal is the forward direction, causing the servomotor to rotate forward.
