With the factory settings, the rotation direction is defined as counter-clockwise (CCW) as viewed from
the output shaft when a pulse train is applied from the MELSERVO-J4 servo amplifier in the direction of
rising position addresses.
This rotation direction can be switched with the MELSERVO-J4 servo amplifier "Basic setting
parameters (‘Pr.PA_ _’)" -> "PA14: Rotation direction selection".
