Technical Manual for EA350 Analog Pulse Type Servo Driver V101 3.4.7.1 Differential input mode of position command pulse Fig. 3-14 Wiring diagram for differential input of pulse command Make sure “2.8V≤ (H level - L level) ≤3.7V”; otherwise the servo driver will have unstable input pulse, resulting in the following circumstances: ➢ Upon input of command pulses, pulse loss occurs. ➢ Upon input of a command direction, a reverse command direction is taken. Caution ☞ 3.4.7.2 Open-collector input mode of position command pulse Wiring for using the internal 24V power source of the servo Fig.
