Functions
Pin 21: +A, 22: −A, 48: −B, 49: +B, 23: +Z, 24: −Z
• Pin 21 outputs the phase-A, phase-B, and phase-Z encoder signals for the Servomotor.
• The encoder outputs conform to the RS-422 communication method.
• The dividing ratio is set in the Encoder Divider Numerator Setting (Pn44) and the Encoder Divider
• The logical relation of phase B to the phase-A pulse is set in the Encoder Output Direction Switch
• The ground for the output circuit line driver is connected to the signal ground (GND). It is not
