The counterclockwise direction (CCW) as viewed from the shaft side is taken as the forward rota-
tion direction of the motors. At this time, if the output pulse of the encoder is B phase lead, set "2:
Quadrature A/B signal (B phase lead)" at Input Terminal [PIA][PIB] Pulse Input Format Selection
(d14).
CCW: Forward
If the output pulse of the encoder is A phase lead, set "3: Quadrature A/B signal (A phase lead)" at
Input Terminal [PIA][PIB] Pulse Input Format Selection (d14).

Additional Information
In the case of a motor that complies with the IEC Standards, forward rotation causes the motor
to rotate clockwise (CW).
Either connect the output pulse of the encoder during forward (CW) rotation so that it becomes
B phase lead, or set Input Terminal [PIA][PIB] Pulse Input Format Selection (d14) to match the
output pulse of the encoder.
