Introduction

  1. RMP40 work probe (spindle): A spindle-mounted wireless probe that communicates with a radio interface.
  2. Work probe stylus: The part of the work probe that touches parts during measurement.
  3. Tool probe stylus : The part of the tool probe that tools touch during measurement. Tools touch the top and side of the stylus when the probe measures tool length and diameter.
  4. RTS tool probe (table): The RTS is a battery-powered, wireless probe.
  5. RMI-QE Optical Machine Interface: The wireless interface for the RMP40 work probe. The RMI-QE uses radio signals to communicate with the CNC control and switch the probe on or off.
  6. RMI cable: This cable connects the RMI to the CNC control.

Work probes for Wireless Intuitive Probe System - Radio Frequency (WIPS -RF) do not work in the wired probe systems (VQCPS) or Wireless Intuitive Probe System - Optical Frequency (WIPS-OF). The work probes can be differentiated by:

  1. The VQCPS work probe (P/N 60-0024) has a square Haas logo.
  2. The WIPS work probe (P/N 60-0050) has a round Haas logo.
  3. The WIPS - RF work probe (P/N 60-0133) has Model RMP40QE writen on the side. 

For installation instructions for both the work probe and tool probe refer to: WIPS - RF - Installation

If the probe up input flickers between 1 and 0 add ferrite filters to reduce noise. 

Batteries

Corrective Action:

Battery replacement is always the first step in probe troubleshooting. Replace both batteries at the same time. Test the batteries before you install them.

 Note: Do not allow coolant or debris to enter the battery compartment.

The life span of the batteries in the probes are shown in the tables below. They must be replaced regularly. If the batteries are low, the work probe's green and blue LEDs may flash. If the batteries are completely dead, the red LED may constantly be on.

Do not rely on a multimeter for testing the batteries. The lithium batteries in the probe may read 3.6 Volts from a multimeter, even though they are low.

Write the date on newly installed batteries for future reference.

 Note: Do not touch the stylus during battery replacement. If the stylus is touched, the probe may power on in the setting mode. Settings can be accidentally changed in this mode.

Interference

Corrective Action:

Turn the work lights off to begin troubleshooting. Make sure the work lights inside the machine are not aimed at the probe or the RMI-QE. Bright lights can interfere with the work probe. Make sure no bright lights are aimed at the machine.

Corrective Action:

Verify there are no objects obstructing the path of the radio frequencies between the RMI-QE, RMP40, and the RTS, as they can interfere with the probe communication.  

Surface Not Found

Corrective Action:

Edit the program to start the probe closer to the part.

Calibration

Corrective Action:

The probes need to be calibrated any time a stylus has been replaced, the tool probe has been moved, or if the CNC control generates alarms during probe routines. The probe needs to be calibrated when changing from inch to metric or metric to inch.

Follow the procedure to calibrate the tool probe and the work probe. Refer to:

The probes must be calibrated in this order:

  1. Tool probe
  2. Work probe length
  3. Work probe diameter

RMP40 Work Probe Settings

Probe Settings Basics

The probe settings are in (3) groups,

  1. Switch-On Method
  2. Switch-Off Method
  3. Enhanced Trigger Filter

The sequence that probe flashes tells you the current probe settings.

 Note: The LEDs flash in different colors and different lengths of time. The sequence that the LED flashes tells you the probe settings. The LEDs flashes a short or a long time. In the tables that follow, a small colored circle  shows that the LED flashes a short time. A rectangle  shows that the LED flashes a long time.

To see what the current probe settings are, do the following:

Remove the batteries from the probe for a minimum of 5 seconds.

Install the batteries.

Important: Do not touch the probe stylus after re-inserting batteries - this is how probe settings are changed. Only touch it later if necessary to change the settings.

After you replace the batteries, the probe LED flashes in a specific sequence.

Look at the probe LEDs. Record the sequence that the LED flashes.

Refer to Renishaw Probe - WIPS-RF - RMP40 - Settings for the meaning of the sequence.

If you would like to change the probe settings, do the following:

Remove the batteries [1] from the probe for a minimum of 5 seconds.

Install the batteries.

Note: Do not touch the probe when installing the batteries, this could alter the probe settings.

Immediately after the LED sequence [2], deflect and hold the stylus [3], the probe will flash Red 8 times.

 Note: If the battery power is low, each red flash will be followed by a blue flash.

Keep the stylus deflected until the "Switch -on Method" setting is displayed. Release the stylus.

To change the probe settings you move the stylus in a specified order, refer to the tables below for the orders for different settings:

 

 

 

 

 

 

The Illustration shows these symbols: The symbols tells you this: This gives this result:
A red arrow that points to the right. Move and hold the stylus for less than (4) seconds. Selects the next option within a group.
A green arrow that points down. Move and hold the stylus for more than (4) seconds. Moves from one group to another.
A white arrow that points down. Do not touch the stylus for (20) seconds or more. Exits the set up.

Default RMP40 settings are the following:

  • Switch On Method: Radio On [1]
  • Switch Off Method: Radio or Spin [2]
  • Enhanced Trigger Filter: Trigger Filter Off [3]

           

RMP40 - Macro Variables.

  • 556: (XRAD) Stylus X calibration radius
  • 557: (YRAD) Stylus Y calibration radius
  • 558: (XOFF) X axis stylus offset (run out)
  • 559: (YOFF) Y axis stylus offset (run out)
  • 566-575: (VRAD) Vector probe radius
  • 576: (LENGTH) Tool offset
  • 577: (OFFSET +  RAD + VRAD) Calibration radius, stylus offset, and vector probe radius total
  • 578: Tool number for the RMP40 probe

RTS Tool Probe Settings

RTS Settings Basics:

The probe settings are in (1) group:

  1. Enhanced Trigger Filter

The LEDs flash in different colors and different lengths of time. The sequence that the LED flashes tells you the probe settings. The LEDs flash a short or a long time. In the tables that follow, a small colored circle  shows that the LED flashes a short time. A colored rectangle  shows that the LED flashes a long time.

To find the current RTS probe settings do the following:

Remove and re-install the batteries. After you install the batteries, the probe LED flashes in a special sequence. These LEDs should show the initial factory settings.

Note: Do not touch the probe when installing the batteries, this could alter the probe settings.

Look at the probe LEDs. Record the sequence of color and length of time that the LED flashes

Refer to Renishaw Probe – WIPS-RF - RTS – Settings for light sequence meanings.

To change the RTS probe settings do the following:

Remove the batteries [1] from the probe for a minimum of 5 seconds.

Install the batteries.

Note: Do not touch the probe when installing the batteries, this could alter the probe settings.

Immediately after the LED sequence [2], deflect and hold the stylus [3], the probe will flash Red 8 times.

 Note: If the battery power is low, each red flash will be followed by a blue flash.

Keep the stylus deflected until the "Trigger filter" setting is displayed. Release the stylus.

Follow the below tables to select the values you want for the settings. Default factory settings are shown in the next set of tables:

 

 

The Illustration shows these symbols: The symbols tells you this: This gives this result:
A red arrow that points to the right. Move and hold the stylus for less than (4) seconds. Selects the next option within a group.
A green arrow that points down. Move and hold the stylus for more than (4) seconds. Moves from one group to another.
A white arrow that points down. Do not touch the stylus for (20) seconds or more. Exits the set up.

Default probe settings are the following:

  • Enhanced Trigger Filter: Trigger Filter Off [1]

           

RTS Macro Variables

  • 582: OTS stylus Z location, non rotating tools
  • 583: OTS stylus Z locations, rotating tools
  • 584: Stylus size for diameter setting
  • 585: X-Axis stylus center location
  • 586: Y-Axis stylus center location
  • 587: Z approach position (This is used in length and diameter probing only). The first fast positioning move to the position where the tool offset is applied (height above stylus).
  • 588: Z clearance position (This is used in length and diameter probing only). The position above the stylus for clearance moves around the stylus (height above stylus).
  • 589: Tools above this diameter rotate (This is used in length and diameter probing only)
  • 590: Maximum cutter diameter size (This is used in length and diameter probing only)
  • 592: Probe orientation. This defines the diameter measuring axis, and the radius offsetting direction for rotating length setting.

RMI-QE Operation:

  1. ACTIVE PROBE (red, green, yellow): There are (4) LEDs that show which probe is currently active.
  2. SIGNAL LED (red, green, yellow): This LED flashes for one second when the RMI-QE sends a start signal to switch on or switch off the work probe or the tool probe.
  3. ERROR (red):  When there is no error the LED will be off. Continuous red light indicates the probe has failed or switched off. Flashing red light indicates a system error or an overload error.
  4. PROBE STATUS (red, green): This bi-color LED is green when the probe is seated, and red when the probe is triggered. The LED flashes red when these is a system error or an overload error.
  5. LOW BATTERY/START LED (red, green, yellow): If the RMI-QE detects a low battery from one of the probes, the low battery LED is on. Replace the batteries in the probes. The LED will be green when the M-code start/stop is in progress. If the battery is low the LED will be yellow when the M-code start/stop is in progress. The LED will flash red when there is an overload error.

For more information refer to Renishaw – WIPS-RF - Radio Machine Interface (RMI) - Lights Information

Dip Switch

Carefully remove the front cover of the RMI-QE to access the Dip Switches.

Verify the Dip Switches match the settings shown in the image

 

Unused Wire

All unused wires from the RMI-QE need to be separated and insulated from each other.

Any exposed wires need to be cut back flush to the insultation. Use heat shrink or electrical tape to secure and insulate them from each other.
