Status
Dedicated output, working status signal port (or second pen signal).
When it is a working state signal, if the port is connected to the relay
externally, the relay coil will be switched on when it is working, and
there will be no impact when the work is suspended. When the work is
finished or cancelled manually, the relay coil will be cut off
。

Wind
Dedicated output. When enabling the fan to control, the port outputs
the fan control signal; otherwise, it is the first pen control signal. When
fan is connected and fan control enables, fan switches can be set on
each layer. If external relays are connected, the relay coil is switched
on when fan is on and the relay coil is cut off when wind is off.

+24V
Power output (if the main power interface is powered by 24V , the pin
is 24V; if the main power interface is powered by 36V , the pin is 36V)
All output signals are isolated by optocoupler. The OC gate output, maximum
drive capacity is 300mA, it can drive 6V/24V relay directly.

input, foot switch input port. Connection mode: when
the foot pedal is pressed, input low voltage signal to the port.
When the foot pedal is released, disconnect the port or input
high voltage signal to the port. If the current machine is in idle
state, the work will be suspended. If the current machine is in
suspended state, the suspended work will be restarted. In other
words, the foot pedal switch and the "start/pause" key on the
keyboard have similar functions. If the time between the second
