Six, control signal wiring
When single terminal connection is adopted for control signal, the wiring diagram is shown as follows:
Note: when VCC is 5V, R short-circuit;
When VCC is 12V, R is 1K and the resistance is greater than 0.125w.
When VCC is 24V, R is 2K and the resistance is greater than 0.125w.
The resistance must be connected to the control signal.
When the control signal adopts differential wiring mode, the wiring diagram is shown as follows:
Vii. Installation size
Viii. Wiring diagram
Typical wiring diagram of the servo system is as follows:
This driver can supply +5V, Max 80mA power to the encoder.Using four times frequency counting method, the encoder resolution multiplied by four is the number of pulses per revolution of the servo motor.
