EA180 Series Servo Drive Users Manual 3.3.2 Servo motor side encoder terminal definition There are 4 types of encoder terminals on the servo motor side. Notes for encoder wiring: 1) Make sure that the drive side and motor side shield layers are reliably grounded, otherwise drive alarms will be caused. 2) Ensure that the differential signal corresponds to the cores in the twisted pair of the connecting cable. For example, A + and A- are a set of differential signals, and a twisted pair should be used. 3) When a 17-bit incremental encoder is used, there are no VD + or VD- signals.
4) When a 17/23-bit encoder is used, please use a cable with a cross-sectional area of 0.2 mm 2 if the wire length is less than 5 meters. If the wire is more than 5 meters, the cross-sectional area of the wire core shall be increased by 0.05 mm 2 for every additional meter.
