OMP400 basics2.1IntroductionWelcome to the OMP400, Renishaw's ultracompact probe for small to medium machiningcentres that sets new standards for reliabilityand robustness in the harshest of machine toolenvironments.Successfully combining the miniaturisation ofthe popular OMP40 with the high accuracy ofthe MP700, the OMP400 provides existing probeusers with a simple upgrade to solid-state straingauge technology and all the associated benefitsthis brings: excellent 3D performance to allow probingof contoured surfaces; improved repeatability in all probingdirections; low pre-travel variation to provide highaccuracy, even when used with long styli; a proven ten-fold improvement in life(10 million triggers); the elimination of reseat failures; high resistance to machine tool vibration; a 360 optical ‘switch-on’ facility, allowing theprobe to be turned on / reset in any position; resistance to shock and false triggeringthrough the use of digital filtering; full compatibility with Renishaw’s industryproven optical transmission systems.In addition to providing high accuracymeasurement on your machine tool, the OMP400also offers: Faster calibration:On complex 3D parts, it is common tomeasure in several different directions.Each direction of a standard mechanicalprobe must be calibrated to ensure that thepre-travel variation is compensated in themeasurement. Performing this calibration forevery 3D direction can be time-consuming.The OMP400 has almost no pre-travelvariation, so a single calibration valuemay be used for any probing angle in 2Dor 3D. This results in a vastly reducedcalibration time. An additional benefit is acorresponding reduction in errors introducedby environmental changes within themachine during a long calibration cycle.
OMP400 basicsOMP400 installation guide2.2Optical transmission methodTwin probe systemThe OMP400 can be operated in either legacyor modulated mode. The modulated mode hasa higher resistance to light interference. Certainforms of light interference can cause false triggersor mimic a start signal and falsely activate theprobe. These effects are much reduced whenmodulated transmission is selected.To operate a twin probe system, one probeneeds to be set to PROBE 1 start and the otherset to PROBE 2 start. These settings are userconfigurable.Legacy modeWhen set to legacy mode, the probe will onlyfunction with an OMI or OMM / MI 12.If start problems are experienced in legacy mode,activate the Legacy Start Filter ON option. Thisintroduces a 1 second delay to the probe switchon time, and improves the probe's resistance tofalse starts caused by light interference.NOTE: The probing program on the machine willneed to take account of this delay.Modulated modeWhen set to modulated mode, the probe will onlyfunction with an OMI-2, OMI-2T OMI-2H orOMI-2C interface.Modulated transmission is capable of providingtwo different coded start signals. This allows theuse of two probes with one interface. Twin probeinstallations require an OMI-2T interface.In a twin probe system, such as a spindle probeand an optical tool setting probe, the spindleprobe would be set to PROBE 1 start and the toolsetter to PROBE 2 start.NOTE: When used in conjunction with an OMI‑2T,the OMP400 switch on method must be set tooptical on (standard).Trigger Logic Trigger Logic (see Section 4 - Trigger Logic )is a method that allows the user to view and selectall available mode settings in order to customisea probe to suit a specific application. TriggerLogic is activated by battery insertion and usesa sequence of stylus deflection (triggering) tosystematically lead the user through the availablechoices to allow selection of the required modeoptions.Current probe settings can be reviewed bysimply removing the batteries for a minimum of5 seconds, and then replacing them to activatethe Trigger Logic review sequence
Configurable settingsThe OMP400 probe can be in one of threemodes.Switch-on delayStand-by mode: where the probe is awaiting aswitch-on signal;Operational mode: activated by one of theswitch-on methods described later in thissection. In this mode the OMP400 is ready foruse.Configuration mode: where Trigger Logic may be used to configure the following probesettings.When the standard switch-on is selected, theprobe will be operational in less than 0.8 seconds.After being switched on, the OMP400 mustremain operational for a minimum of 1 secondbefore being switched off.A second switch-on mode is available wherea 3 second delay is invoked after the probestart signal is received. This feature is aimed atmachines where 'Auto-start' is required, i.e. itwill ensure that when the probe receives a startsignal during a tool change, it will switch-oncorrectly in the spindle. To ensure that the probeactivates correctly, it is important to make surethat it is stationary when it is switched on. If theprobe is not stationary during a start sequence,there is a possibility that the strain gauges couldauto-zero in the incorrect position and produce apermanently triggered output. The 3 second delayensures that the start sequence only occurs whenthe probe is safely located in the machine spindle(this assumes that the tool change process iscompleted in less than 3 seconds).NOTES:The probing program on the machine will need totake account of this delay.When used in conjunction with an OMI‑2T, theOMP400 switch on method must be set to opticalon (standard).OMP400 basicsModes of operation2.3
OMP400 basicsOMP400 installation guide2.4Switch-on / switch off methodsEnhanced trigger filterThe following switch-on / switch-off options areuser-configurable.Probes subjected to high levels of vibration orshock loads may output signals without havingcontacted any surface. The enhanced trigger filterimproves the probe's resistance to these effects.1.Optical on / Optical off.2.Optical on / Timer off.NOTE: A visual indication of currently selectedprobe settings is provided, on battery insertion,by the three multicoloured LEDs located withinthe probe's window (see Section 4 - TriggerLogic ).When the filter is enabled, a constant 8 or 16 msdelay is introduced to the probe's output. Theprobe is factory set to 8 ms. If false triggering isnoticed then consider increasing the filter delay to16 ms.NOTES:It may be necessary to reduce the probe'sapproach speed to allow for increased stylusovertravel during the extended time delay.Whilst there is also a 0 ms setting, this isfor Renishaw's use only. Renishaw does notrecommend that you use this setting as falsetriggering is likely to occur.OMP400 switch-onmethodOMP400 switch-off methodSwitch-off options areconfigurableSwitch-on timeOptical onOptical switch-on iscommanded by machineinput.Optical offOptical switch-off is commanded bymachine input.A timer automatically switches theprobe off after 90 minutes from lasttrigger if not turned off by machineinput.Legacy filter off:0.8 secondsLegacy filter on:1.6 secondsModulated0.7 seconds.Timer off (time out)Time out will occur (12, 33 or 134seconds - user configurable) afterthe last probe trigger or reseat.Optical on (3 seconddelay)Optical switch-on iscommanded by machineinput.Timer off (time out)Time out will occur (12, 33 or 134seconds - user configurable) afterthe last probe trigger or reseat.3 seconds.NOTE: After being switched on, the OMP400 must be on for 1 second before being switched off.
The Auto-reset function in the OMP400compensates for stylus forces, due to highaccelerations and changes in probe orientation,that can cause the probe to trigger when usinglong styli ( 100 mm).This feature is suitable for radial rotations(e.g. vertical to horizontal). It is selectable usingTrigger Logic .NOTE: The Auto-reset function cannotcompensate for rotations around the probe'saxis when horizontal with long styli ( 100 mm). Amanual reset will be required in this situation.When a manual reset is required, the methodused will depend on the probe's switch-off setting: In optical off mode, the probe must beswitched off then on again. In timer off mode, the probe must beswitched on using an M code start signal.Optical transmission method andprobe identityThe OMP400 can be operated in either legacyor modulated mode. The modulated mode hasa higher resistance to light interference. Certainforms of light interference can cause false triggersor mimic a start signal and falsely activate theprobe. These effects are much reduced whenmodulated transmission is selected.Legacy modeWhen set to legacy mode, the probe will onlyfunction with an OMI or OMM / MI 12.If start problems are experienced in legacy mode,activate the Legacy Start Filter ON option. Thisintroduces a 1 second delay to the probe switchon time, and improves the probe's resistance tofalse starts caused by light interference.NOTE: The probing program on the machine willneed to take account of this delay.Modulated modeWhen set to modulated mode, the probe will onlyfunction with an OMI-2, OMI-2T OMI-2H orOMI-2C interface.For most applications, the spindle probe shouldbe set to PROBE 1 start.PROBE 2 start should only be selected fora secondary spindle probe in a twin probeapplication.Optical powerWhere the separation between the OMP400 andthe receiver is small (no more than 2 m), the lowoptical power setting may be selected.

However,the maximum force applied tothe component will occur afterthe trigger point and will begreater than the trigger force. Themagnitude depends on a numberof factors affecting probe overtravelincluding measuring speed andmachine deceleration. If theforces applied to the componentare critical, contact Renishaw forfurther information. 11 6 mm (0.23 in)* Performance specification is for a test velocity of 240 mm/min (9.45 in/min) with a 50 mm carbon fibre stylus. Test velocity does not constrain performance in application.§ Stylus overtravel force in XY plane occurs 70 µm after the trigger point and rises by 0.1 N/mm, 10 gf/mm (9.1 oz/in) until the machine tool stops (in the high forcedirection and using a 50 mm carbon fibre stylus).† Stylus overtravel force in Z direction occurs 10 µm to 11 µm after the trigger point and rises by 1.2 N/mm, 122 gf/mm (109.6 oz/in) until the machine tool stops.OMP400 basicsOMP400 specification2.7
