Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Wiring for using an external 24V power source and internal current-limiting resistor of the driver Fig. 3-16 (a) Wiring diagram for open-collector input of pulse command (using an external power source and the internal current-limiting Wiring for using an external 24V power source and external current-limiting resistor resistor) Fig. 3-16 (b) Wiring diagram for open-collector input of pulse command (using an external power source and external current-limiting resistor) The current-limiting resistor R1 is selected as follows: Resistor R1 shall be selected to satisfy the formula: Recommended resistance for R1: 1.
A pair of differential signals shall use a twisted-pair cable. 2. The pulse input signal cable must be run separately from the power cable, with at least 30cm or greater spacing. 3. The pulse input interface is not a shielded input interface. To reduce noise disturbance, it is recommended to connect the output signal ground of the upper computer and the signal ground of the driver.
