1. 6 0 ESPECIAL FUNCTIONS 6 1 Safety Charge Pump SCP Pin 17 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 be 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 configures it as is shown in the Fig 8 Next press the apply button User s Manual Page 5 Engine Configuration Ports amp Pins Current Hi Low Output 7 Output 8 Output 9 Pins 2 9 1 14 16 and 17 are output pins No other pin numbers should be used Aceptar Aplicar Fig 1 Charge Pump configuration Selecting the SCHP operation mode The Safety Charge Pump can be activated or deactivated depending on the jumper position Note When the Safety Charge Pump is activated the
