10The RMP60 probe can be in one of three modes:1. Stand-by mode - The RMP60 is waiting fora switch-on signal .2. Operating mode - Activated by one of theswitch on methods described on this page.In this mode and the RMP60 is now readyfor use.3. Configuration mode - The trigger-logicconfiguration method allows a number ofRMP60 set-up options to be configured bytriggering the RMP60, including the switch-offoptions described on page 25.Modes of operationModes of operation RMP60 switch-onRMP60 power on/offSwitch-on options are configurable - see page 13.Three switching methods can be used.1. Radio startRadio switch-on is commanded byM code.2. Spin startSpin at 650 rev/min for 1 sec minimum(maximum 6 sec)3. Shank switchNote:RMP60 will be turned on after 1 sec in allmodes.
11Modes of operation RMP60 switch-offSwitch-off options are programmableThree switching methods can be used.1. Radio stopRadio switch off is commanded by aM code.(Only applies when radio turn on isselected).A timer automatically switches the probe offafter 90 min from last trigger if not turned offby M-code.2. Timer off (time out)(Only applies when radio on/spin onmode is selected).The RMP60 will time out (12, 33 or134 sec) after the last probe trigger orreseat.3. Spin stop(Only applies when spin on mode isselected).A timer switch automatically swichesthe probe off after 90 min from lasttrigger off, if not spun off.4. Shank switch(Only applies when shank on mode isselected).Note:After being turned on, the RMP60 must beon for a minimum of 1 sec (7 sec for spinoff) before being turned off.

15Setup is done by using the RMP60 trigger logicand powering on the RMI at a particular timeduring the process.Trigger logic is a method that allows userconfiguration of the options available in theRMP60. Trigger logic uses a sequence ofRMP60 triggering and battery insertionfollowed by further RMP60 triggering.This leads the user through a series of choicesallowing selection of the required options.Reviewing of choices made can be made bybattery insertion alone. See pages 12 and 13 forfull details of reviewing probe settings andconfiguration using trigger logic.1. Use trigger logic to set RMP60 turn on/ offmodes as desired.2. Use trigger logic to access RMP60acquisition mode (light blue flashes, 2 short1 long).System setup/establishing RMP60-RMI partnership.RMP60-RMI partnership3. Power on the RMI.4. Wait until RMI signal led flashes green.5. Trigger the probe (min 0.1 sec max 2 sec)RMP60 will flash 2 x turquoise short,followed by 1 red long and repeat untilacquistion occurs.6. RMI pattern will change to red & yellowflashing when it acquires the RMP.7. Allow ~10 seconds for both RMP60 andRMI to timeout all RMP60 LEDs off and RMIsignal LED off. The system is then ready foruse.WarningWhen holding the RMP60 do NOT wrapa hand, or anything else, around theglass window.!continued on next page
16Note.When the RMP60 and RMI become partners theRMI records the RMP60 serial number. It is notpossible for an RMI to be partners with morethan one RMP60.It is possible for an RMP60 to be partners withmore than one RMI, but the system will notwork correctly if more than one partner RMI ispowered on at any one time.RMP60-RMI partnership
17RMP60 batteriesReplacing batteriesOnly use specified batteries.Clean and dry RMP60 with a cloth or paper towelbefore removing battery cover. Where theRMP60 has been exposed to coolant, it isrecommended that the area around the batterycover is cleaned.To access the RMP60 batteries, remove thebattery cover by rotating the securing screw30° anticlockwise and withdraw battery cassette.Take care to avoid damaging the cover gasket.When inserting the batteries, ensure they areloaded as shown (see next page).If one or more batteries are incorrectly loadedthe probe will not respond.RMP60 batteriesDo not mix new and used batteries or batterytypes, as this will result in reduced life anddamage to the batteries.Always ensure that the cover gasket and matingsurfaces are clean and free from damage, beforereassembly.

IF A RMP60/SHANK UNIT IS ACCIDENTALLYDROPPED, IT SHOULD BE CHECKED FORON-CENTRE POSITION.3. DO NOT HIT OR TAP THE PROBE TOACHIEVE ON-CENTRE ADJUSTMENT.Stage 1 RMP60/shank mountingIf the RMP60 does not have a shank switch,please proceed from note 3.1. Remove plug from rear of RMP60 using pliars.2. Place bobbin into shank.3. Fully slacken four screws A.4. Grease two screws B, and fit into shank.5. Fit RMP60 onto the shank, and visuallyposition centrally.6. Tighten screws B to 6-8 Nm (4.4- 5.9 lb.ft)(Partially tighten screws B to 2 - 3 Nm(1.47 - 2.2 lbf.ft), if RMP60 is to be on-centreadjusted).7. The RMP60 assembly is ready for use.BABobbinSwitch
22Stylus on-centre adjustment (if required)Stylus on-centre adjustmentStage 2 On-centre adjustment8. Each of the four screws A will move theprobe relative to the shank, in the X or Ydirection as pressure is applied.Tighten individually, backing off aftereach movement.9. When the stylus tip run-out is less than20 µm, fully tighten screws B to 6 - 8 Nm(4.4 - 5.9 lbf.ft).10. For final centering use screws A to movethe RMP60, progressively slackening onone side and tightening the opposite screw,as the final setting is approached, usingtwo hexagon keys.Tip run out of 5 µm (0.0002 in) shouldbe achievable.11. It is important that all four screws A aretight or tightened to 1,5 - 3,5 Nm(1.1 - 2.6 lbf.ft) once the final settinghas been achieved.2,5 mm AF4 mm AFAB
23Stylus trigger force adjustmentStylus trigger force adjustmentSpring force within the probe causes thestylus to sit in one unique position, and return tothis position following each stylus deflection.Stylus trigger force is set by Renishaw. The usershould only adjust trigger force in specialcircumstances e.g. excessive machine vibrationor insufficient force to support the stylusweight.To adjust trigger force, and turn the adjustingscrew anticlockwise to reduce force (moresensitive) or clockwise to increase force(less sensitive). A stop prevents damage, whichcould be caused by overtightening the adjustingscrew.2 mm AFReduceforceIncreaseforce
24Probe movesProbe triggerA probe trigger signal is generated when theprobe’s stylus is driven against a surface.The machine control records the contactposition and instructs machine motion to stop.To ensure a trigger signal, drive the probeagainst the workpiece to a target beyond theexpected surface, but within the limits of stylusovertravel. After the probe stylus touches thesurface, reverse clear of the surface.Single and double touch probingIf the probe operating sequence is based on asingle touch, then the probe is returned to itsstart point following a measuring move.On some types of controller, it is desirable touse a two touch method, as poor accuracy andrepeatability can result at higher feed rates.With a double touch sequence the first move findsthe surface quickly. Then the probe is backed offto a position clear of the surface, before makingthe second touch at a slower feed rate, therebyrecording the surface position at a higherresolution.Probe measuring speedThe probe system transmission delay time issmall and constant. It does not normally limit theprobing speed, because it is cancelled out duringcalibration of the probe on the machine tool.High probing speeds are desirable, however ifused, a probing velocity must be chosen whichallows the machine to stop within the limits ofstylus overtravel, and measuring capability ofthe machine.Probe moves
25Calibrating a systemCalibration should be done in the followingcircumstances:1. Before the system is used2. When a new stylus is used.3. To allow for machine thermal growth.4. Poor relocation repeatability of the probeholder with machine spindle.It is important that calibration cycles are run atthe measuring cycle feed rate to cancel outsystem errors.Calibration measurements should be made inevery measuring direction to provide completecalibration data for the measuring cycles.Probe interface signals1. Error signal delayA delay of 28 ms maximum for the RMI, willelapse between an error occurring and theoutput indicating error.2. Probe signal delayThere is a nominal delay of 10 ms with avariation of ±10 µs for an interface, from the timethe probe actually operates, to the RMI interfaceoutputting a probe change of state.Probing cycles are available from RenishawX/YZX/YProbe moves
26Verify your softwareDoes your software have suitable calibrationroutines which compensate for stylus on-centreerrors? If not, you must set the probe styluson-centre mechanically.Note: Machining centre applications :When using probe styli which are not on spindlecentre, spindle orientation repeatability isimportant to avoid probe measurement errors.Software requirementsProbing cycles and features are machinesoftware dependant. Good software will allow thefollowing functions :●Simple to use cycles●Update a tool offset●If an out of tolerance is found, eithergenerate an alarm stop, or set a flag forcorrective action●Update work co-ordinate systems forpositioning●Print data in the form of an inspectionreport to an external PC / printer●Set tolerances on featuresSoftware requirementsInspection cycle featuresSimple to use canned cycles for standardfeatures :Bore/boss.
