Definition and functional description of all onboard interfaces

There are 10 types of external connectors on the board, divided into five categories: main control, servo specific, universal IO, laser/trigger/brake, and power emergency stop. The functions of each interface are as follows:

Dial switches S1 and S2 function

Two sets of dialing codes, S1 and S2, are used on the board to switch the ALM-RST pin function of the CMP interface:

ON: The pin function of this channel is servo alarm reset signal (default OFF)

OFF: This channel is a universal digital output DO

S1 controls 1/2 axis, S2 controls 3/4 axis, and the four axes switch modes independently.

Expand IOIF isolation IO: DI side common DIO24V connected to external 24V; DO side common DIOGND connected to external 24V ground. When using DO, an external 24V power supply must be connected

Explanation of all signal isolation circuits and wiring schematics

The document provides 11 types of signal internal isolation circuits, all of which use optocoupler isolation (PS2805, PS2802) to achieve electrical isolation between the 5V digital domain of the motion card and external 24V devices, anti-interference:

EMG Global Emergency Stop Input (J5): Recommended for normally closed Class B switches, which block all pulse outputs after triggering and minimize switch load 24V@6mA Optocoupler PS2805 isolation

Limit/Origin/Axis EDI Isolation Input (J1/J2 MEL/PEL/ORG/EDI): Same as the EMG input circuit, one end of the external switch is connected to IGND, the other end is connected to the signal pin, and the common DICOM is connected to 24V

Servo feedback input ALM/INP/ZSP (CMP): optocoupler isolation, servo output collector open circuit signal pulls down IGND trigger input
