MASSO Documentation
17.1. Proma Compact THC 150
MASSO supports THC control signals to easily connect different types of THC's. THC's that are designed for
to control Z axis directly using STEP and DIRECTION signals are not supported.
INFORMATION: Before the Z axis can be automatically controlled by THC, THC control must be
enabled via gcode commands and proper sequence of commands must be executed.
Control signals
Plasma Arc OK Signal - This signal is required to tell MASSO that the arc has been successful. This
signal should go HIGH by the THC on successful arc start. Wire this to one of the inputs on MASSO
and assign the input as Plasma Arc OK Signal.
Z Up Signal - When this signal goes HIGH the Z axis is moved up. Wire this to one of the inputs on
MASSO and assign the input as THC Input - 1.
Z Down Signal - When this signal goes HIGH the Z axis is moved down. Wire this to one of the
inputs on MASSO and assign the input as THC Input - 2.
Information: THC Input - 3 & THC Input - 4 are not used at this time.
PROMA 150 wiring example
INFORMATION: The below wiring example is how its recommended by PROMA 150
manufacturers. As plasma sources induce high voltages and electrical noise, its very important to
do the proper wiring and used shielded wires.
