Section 1: Overview 13
PHC to CNC Signals
All signals to the CNC are connected through the 25-pin D subconnector on the control unit. For detailed
interfacing information, see PHC Interface Signals on page 29 and CNC Interface Signals on page 30.
Outputs to CNC:
Digital IHS complete output
Digital motion output
Digital retract complete output
Digital error output/torch collision
Inputs from CNC:
Digital cycle start input
Digital corner hold input
Digital IHS sync input
Interlock
PHC to Plasma Signals
All signals to the plasma interface are connected through the 15-pin D subconnector on the control unit. These
signals are easily connected through the plasma interface unit or directly to a Powermax
®
G3 supply using a
G3 interface cable. For more detailed information, see Plasma Interface Assembly on page 16.
Outputs to plasma:
Digital plasma start output
Digital hold ignition output
Inputs from plasma:
Digital transfer input
Analog attenuated arc voltage
PHC to Lifter Signals
All signals to the lifter are connected through the 9-pin D subconnector on the control unit. For more detailed
information, see Standard Lifter Assembly on page 17.
Inputs from lifter:
Digital upper limit switch
Digital lower limit switch
Digital breakaway switch
Analog tip touch sense
PHC to Lifter Power Connections
All power connections to the lifter are coupled through the 7-pin circular connector on the control unit. For
more detailed information, see Standard Lifter Assembly on page 17.
Outputs to Lifter:
Motor drive 24V PWM
Power off brake 24Vdc
