MASSO supports THC control signals to easily connect different types of THC's. THC's that are designed 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 a proper sequence of commands must be executed.
- 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
WARNING: Use a separate power supply to power your THC unit as shown in the example below. Failure to do so can result in noise-related issues and in case of THC failure damage to MASSO as using the same power supply bypasses input optical isolation.
INFORMATION: The below wiring example is how its recommended by PROMA 150 manufacturers. As plasma sources induce high voltages and electrical noise, it's very important to do the proper wiring and used shielded wires.
