Safety Charge Pump "Schp". (Pin 17) - CNC4PC C11G User Manual

Safety Charge Pump "SCHP". (Pin 17).

5.4
This board takes advantage of Mach ability to send a specific frequency through one of
the pins of the parallel port when the program is in control of the system. CNC
machinery can be very dangerous, and you could have a risk of the machine doing
something different that what you intend the machine to do if the program loses control
of your system. Mach can be programmed in a way, so when it is "in control", it delivers
a 12.5 KHz signal through one of the pins. This card lets you use this signal to work as
an On/Off switch for your system, enabling a powerful safety system for your
equipment. If you ever had windows crash on you, then this card is for you. The port
can also do weird things while the system is coming up, or down.
For Configuring the Charge Pump in Mach X: Use the dialog Config / Ports and
pins / Output Signals. Enable the Charge Pump output and configure it as is shown in
the Fig. 8 Next, press the apply button.
