Note: In order to resist interference, twisted-pair shielding wire must be used.
Note:
(1) The power supply voltage range of P- / P+ 24V and D- / D+ 24V is 18V ~ 25V. The power
supply voltage range of P- / P+ 5V and D- / D+ 5V is 3.3V ~ 5V. If it is lower than 18V / 3.3V, there
may be abnormal pulse and direction.
(2) Servo pulse input port is ON for 10mA.
(3) If the controller is Xinje PLC, the rated current of the pulse output port is 50mA. According to
this data, it can be judged that one pulse theoretically can drive at most five servos. It is recommended
not to exceed 3.
3.2.2 SI input signal
Please use a relay or an open collector transistor circuit to connect. When using relay connection,
please select the relay for small current. If the relay is not small current, it will cause bad contact.
