The controller supports 0~10V analog voltage signal output for controlling the VFD (Variable Frequency Drive) spindle speed,
as well as M3 and M4 signals for controlling the VFD spindle rotation direction,
If you have a standard spindle (controlled only through a power switch), please refer to Output Port Relay Control and use the M3 spindle switch port for control
If using a laser,
or a switch spindle with speed adjustment through a MOS transistor, connect the PWM signal and share GND with the controller,

Note: The 0-10V analog voltage is converted from a 0-5V PWM signal through an operational amplifier,
