10 Modes of operation Modes of operation The RMP60 probe can be in one of three modes: 1. Stand-by mode - The RMP60 is waiting for a switch-on signal . 2. Operating mode - Activated by one of the switch on methods described on this page. In this mode and the RMP60 is now ready for use. RMP60 switch-on RMP60 power on/off Switch-on options are configurable - see page 13. Three switching methods can be used. 1. Radio start Radio switch-on is commanded by M code. 2. Spin start 3.
Modes of operation RMP60 switch-off Switch-off options are programmable Three switching methods can be used. 1. Radio stop Radio switch off is commanded by a M code. (Only applies when radio turn on is selected). A timer automatically switches the probe off after 90 min from last trigger if not turned off by M-code. 3. Spin stop (Only applies when spin on mode is selected). A timer switch automatically swiches the probe off after 90 min from last trigger off, if not spun off. 4.

RMP60-RMI partnership 15 System setup/establishing RMP60-RMI partnership. Setup is done by using the RMP60 trigger logic and powering on the RMI at a particular time during the process. Trigger logic is a method that allows user configuration of the options available in the RMP60. Trigger logic uses a sequence of RMP60 triggering and battery insertion followed by further RMP60 triggering. This leads the user through a series of choices allowing selection of the required options.
16 RMP60-RMI partnership Note. When the RMP60 and RMI become partners the RMI records the RMP60 serial number. It is not possible for an RMI to be partners with more than one RMP60. It is possible for an RMP60 to be partners with more than one RMI, but the system will not work correctly if more than one partner RMI is powered on at any one time.
RMP60 batteries 17 RMP60 batteries Replacing batteries Only use specified batteries. Clean and dry RMP60 with a cloth or paper towel before removing battery cover. Where the RMP60 has been exposed to coolant, it is recommended that the area around the battery cover is cleaned. To access the RMP60 batteries, remove the battery cover by rotating the securing screw 30° anticlockwise and withdraw battery cassette. Take care to avoid damaging the cover gasket.
18 RMP60 batteries - + Battery cover + Batteries 2 x AA DO NOT leave exhausted batteries in probe DO NOT allow coolant or debris to enter the battery compartment DO check for correct battery polarity ! Please dispose of exhausted batteries in accordance with local regulations. Do not dispose of batteries in fire.
Battery life expectancy 19 Battery life expectancy Replace the batteries as soon as is practicable. Alkaline - Two AA type (see page 20). Typical battery reserve life Using the standard alkaline battery at 5 % usage, typically the probe will continue to operate for approximately 2 weeks after a low battery warning is first indicated. BATTERY Two AA type Alkaline SHANK/SPIN TURN ON When inserting new batteries the RMP60 will flash to show current configuration (page 12).
20 Battery life expectancy Low battery indicators The low battery warning will be signalled by the alternate blue flashing of probe status LED when the end of the usable battery life is approaching. Simultaneously, the low battery LED on the RMI will be lit. Dead battery indicators When the battery voltage drops below the threshold where performance can be guaranteed, the RMP60 probe status LED will change to constant red.

Stylus trigger force adjustment Stylus trigger force adjustment Spring force within the probe causes the stylus to sit in one unique position, and return to this position following each stylus deflection. Stylus trigger force is set by Renishaw. The user should only adjust trigger force in special circumstances e.g. excessive machine vibration or insufficient force to support the stylus weight.
24 Probe moves Probe moves Probe trigger A probe trigger signal is generated when the probe’s stylus is driven against a surface. The machine control records the contact position and instructs machine motion to stop. To ensure a trigger signal, drive the probe against the workpiece to a target beyond the expected surface, but within the limits of stylus overtravel. After the probe stylus touches the surface, reverse clear of the surface.
Probe moves 25 It is important that calibration cycles are run at the measuring cycle feed rate to cancel out system errors. Z Calibration measurements should be made in every measuring direction to provide complete calibration data for the measuring cycles. Probe interface signals X/Y X/Y 1. Error signal delay Probing cycles are available from Renishaw Calibrating a system Calibration should be done in the following circumstances: 1. Before the system is used 2. When a new stylus is used. 3.
26 Software requirements Software requirements Probing cycles and features are machine software dependant. Good software will allow the following functions : Verify your software Does your software have suitable calibration routines which compensate for stylus on-centre errors? If not, you must set the probe stylus on-centre mechanically.
