MachPro Waterjet Setup Manual

{{@2007#bkmrk--1}}

Introduction

Configure your motion controller including: axis calibration, homing, limits, and I/O

Setup the first jet

Every waterjet will need most of following signals for each jet. Map each of the ones you need to the correct output. 

Name	Function
Jet Pump Output	This turns on the actual intensifier pump. If using a PLC this should trigger the PLC to start the intensifier. Often called Intensifier on.
Jet High Pressure Output(s)	Turns on and off high pressure for the corresponding jet. Also called things like UHP On, high pressure on.
Jet Abrasive Output(s)	Turns on and off abrasive for the corresponding jet.
Jet Pressure Output(s)	Turns on and off the actual jet. Often called Water On or Jet On.

Pull down Configure -> Control -> Settings tab

1. In the upper right corner, filter the settings for jet
2. Set Jets Enabled to 1 
3. Configure the software to use your previously mapped signals
   1. Jet Pump Output #1 maps to Pump or Intensifier ON 
   2. Jet Pressure Output #1 maps to Jet Pressure On
   3. Jet Abrasive Output #1 maps to Abrasive On
   4. Jet High Pressure Output #1 maps to High Pressure

Jet Delay SetupSettings

There are default jet delay settings which you may adjust. 

Jet

• ThePressure Delay (ms) “JetPressureDelay”- Turns Jet on, then applies delay, then turns on Abrasive.

  Jet Pre-Off Delay (ms) “JetPreOffDelay”- Applies delay, then turns Jet off.

  Jet Off Delay (ms) “JetOffDelay”- Turns Jet off, then applies delay.

  Jet Pierce Delay (sec) ““JetPierceDelay”- Turns Jet on, then applies delay.

  Jet High Pressure Delay (ms) “JetHighPressureDelay”- When “High Pressure Toggle” is high, it applies the delay, then turns on Jet and Abrasive. No yellow wait bar appears.

  Jet Pump On Delay (ms) “JetPumpAutoOnDelay”- Turns on Pump, applies delay, flashes button until delay is over

  Jet Abrasive Line Delay (ms) “JetAbrasiveDelay”- Turns Jet and Abrasive on at the same time. Then applies the delay. Identical to “Jet Abrasive On Delay” and “Jet Pierce Delay”.

  Jet Abrasive On Delay (sec) “JetAbrasiveOnDelay”- Turns Jet and Abrasive on at the same time. Then applies the delay. Identical to “Jet Abrasive Line Delay” and “Jet Pierce Delay”.

  Jet Abrasive Off Delay (sec) “JetAbrasiveOffDelay”- Turns off Abrasive, applies delay, Turns off Jets. Identical to "Jet Abrasive Purge Line Delay"

  Jet Abrasive Purge line Delay at(ms) 1250“JetAbrasivePurgeDelay”- msTurns whichoff allowsAbrasive, theapplies abrasivedelay, Turns off Jets. Identical to stop“Jet flowing just before the water turns off

• The JetAbrasive Off DelayDelay”.
  to 250 ms which gives us a slight pause after the water turns off and before it starts moving to the next cut

Alarm Setup

Pull down Configure -> Plugins -> Global Monitoring System (GMS)

You may have inputs for Low Inlet Water Pressure. Configure a GMS to monitor this signal as follows:

Servo Abrasive Setup

Some waterjets have a servo controlled Abrasive. For that use these settings:
