  • Page 9: Rmp40 Basics

    Section 2, “RMP60 basics” RMP40 basics Introduction The RMP40 forms part of Renishaw’s family of radio transmission probes. It is ideally suited to large machining centres or where line-of-sight between probe and receiver is difficult to achieve or where Z travel is limited.

  • Page 10: System Interface

    RMP40 installation guide System interface The RMI and RMI-Q integrated interfaces/receivers are used to communicate between the RMP40 probe and the machine controller. Trigger Logic Trigger Logic™ (for more information, see page 4.1, “Reviewing the probe settings”) is a method that allows the user to view and select all available mode settings in order to customise a probe to suit a specific application.

  • Page 11: Enhanced Trigger Filter

    NOTE: After being switched on, the RMP40 must be on for 1 second minimum. When using spin on / spin off, ensure that the probe is stationary for 1 second minimum after it has stopped spinning before using spin on.

  • Page 12: Multiple Probe Mode

    Multiple probe mode The RMP40 can be configured, using Trigger Logic, to allow multiple radio probes to be used with a single RMI or RMI-Q. NOTES: The “radio on” switch-on method cannot be used in “multiple probe mode”. “Multiple probe mode”...

    This allows easy installation, either inside or outside the machine enclosure. Coolant and swarf residue accumulating on the RMP40 and RMI or RMI-Q may have a detrimental effect on transmission performance. Wipe clean as often as is necessary to maintain unrestricted transmission.

  • Page 18: Positioning The Rmp40 And Rmi Or Rmi-Q

    RMI or RMI-Q is unpowered in “radio-on” (radio-off or timer-off) configurations. The RMP40 goes into “hibernation mode” 30 seconds after the RMI-Q is unpowered (or the RMP40 is out of range). When in “hibernation mode”, the RMP40 checks for a powered RMI or RMI-Q every 30 seconds. If found, the RMP40 goes from “hibernation mode”...

  • Page 23: Calibrating The Rmp40

    Calibrating the RMP40 Why calibrate a probe? A spindle probe is just one component of the measurement system which communicates with the machine tool. Each part of the system can introduce a constant difference between the position that the stylus touches and the position that is reported to the machine. If the probe is not calibrated, this difference will appear as an inaccuracy in the measurement.

  • Page 24: Calibrating The Probe Length

    Calibrating the probe length Calibrating a probe on a known reference surface determines the length of the probe, based on the electronic trigger point. The stored value for length is different from the physical length of the probe assembly. Additionally, the operation can automatically compensate for machine and fixture height errors by adjusting the probe length value that is stored.

    Changing the probe settings Insert the batteries or, if they have already been installed, remove them for five seconds and then refit them. Following the LED check, immediately deflect the stylus and hold it deflected until five red flashes have been observed (if the battery power is low, each red flash will be followed by a blue flash).
  • Page 29 Further probes used require the same “Multiple probe mode” setting, but do not need to be partnered with the RMI or RMI-Q. To partner an RMP40 with an RMI see page 4.6, “RMP40 – RMI partnership”, or with an RMI-Q see page 4.7, “RMP40 – RMI-Q partnership”, for further information. Once acquisition has been successful, the RMP40 will revert to “...

  • Page 30: Rmp40 - Rmi Partnership

    System set-up is achieved using Trigger Logic and powering the RMI. Partnering is only required during initial system set-up. Further partnering will be required if either the RMP40 or RMI is changed, or if a system is reconfigured for multiple probes (“multiple probe mode”).

  • Page 31: Rmp40 - Rmi-Q Partnership

    RMP40 – RMI-Q partnership System set-up is achieved by using Trigger Logic™ and powering on the RMI-Q. Alternatively, partnering to a RMI-Q can be achieved by using ReniKey; a Renishaw machine macro cycle which does not require the RMI-Q to be power cycled.

  • Page 33: Maintenance

    Wipe the window of the probe with a clean cloth to remove machining residue. This should be done on a regular basis to maintain optimum transmission. CAUTION: The RMP40 has a glass window. Handle with care if broken to avoid injury.

  • Page 34: Changing The Batteries

    Changing the batteries CAUTIONS: Do not leave dead batteries in the probe. When changing batteries, do not allow coolant or debris to enter the battery compartment. When changing batteries, check that the battery polarity is correct. Take care to avoid damaging the battery cassette gasket. Only use specified batteries.
  • Page 35 NOTES: After removing the old batteries, wait more than 5 seconds before inserting the new batteries. Do not mix new and used batteries or battery types, as this will result in reduced life and damage to the batteries. Always ensure that the cassette gasket and mating surfaces are clean and free from dirt before reassembly.
