Technical Manual for EA350 Analog Pulse Type Servo Driver V101 3.3.2 Definition of encoder terminals on the servo motor side On the servo motor side, there are four forms of encoder terminals Precautions for encoder wiring: 1) Do reliably ground the shielding screens on the driver side and the motor side; otherwise a warning of the driver will be triggered. 2) Make sure the differential signal corresponds to two core wires of the twisted-pair connecting cable. For example, SD+ and SD- forming a differential signal group shall use a twisted-pair cable.
3) When a serial incremental encoder is selected, VD + and VD- signals do not exist (VD+ and VD- are the positive and negative ends of a battery) 4) When a 17/23-bit serial encoder is used with a conductor of less than 5m long, a cable with the cross section area of 0.2mm 2 shall be used. If the conductor exceeds 5m, per each incremental 1 meter, the cross area of the core wire shall increase by 0.05mm 2 . Caution ☞ Please note that for the encoder cable provided by us, the connection method for the shielding layer differ from those mentioned above. When an absolute encoder is used, please choose disposable ER14505 3.6 V lithium batteries.
