Rotation Direction Change (7: DIR)
To set up the mechanical configuration so that a + voltage input causes reverse rotation instead of for-
ward rotation, this terminal can be connected to the E0V terminal for any of pins 1 through 3 (encoder
power supply GND terminal). This function carries out the same operation by means of setting setup
parameter Cn-02 bit no. 0 to “1.” Use this to prevent runaway when replacing the Servo Driver.
