Name | Function |
| 1 | PU+ | Pulse control signal: the rising edge of the pulse is valid; PU- is 3.3~5V at high level, and 0-0.5V at low level. For reliable response to pulsed signals, the pulse width should be greater than 1.2μs. If +12V or +24V is used, a series resistor is required. |
| 2 | PU- | |
| 3 | DIR+ | Direction signal: high/low level signal, in order to ensure the reliable commutation of the motor, the direction signal should be established at least 5μs before the pulse signal.DIR-3.3~5V at high level, 0-0.5Vat low level. |
| 4 | DIR- | |
| 5 | WR+ | Alarm signal output, the internal output is optocoupler NPN.Normally,it is in high impedance state, and it is connected to COM during alarm. |
| 6 | OZ | Encoder zero output. There is a zero signal optocoupler NPN output conduction signal. |
| 7 | COM | The output signal is common to the 485 power supply. |
