Introduction
The OMP40-2 is an optical machine tool probe
suitable for use on small to medium machining
and multi-tasking centres. It is designed to resist
optical interference, false triggering and shock.
The OMP40-2 can be operated in either ‘Legacy’
or ‘Modulated’ optical transmission modes – see
probe settings for further details.
When operating in ‘Legacy’ mode, the OMP40-2
is compatible with an OMM receiver and an MI 12
interface, or with an OMI receiver/interface.
In ‘Modulated’ mode, the OMP40-2 becomes
compatible for use with an OMM-2 receiver and
an OSI interface, or with an OMI-2 / OMI-2T /
OMI-2H receiver/interface, to provide substantially
increased resistance to light interference.
In ‘Modulated’ mode, it is possible to define the
probe ID. This is factory set to PROBE 1, but can
be changed to PROBE 2 for use with twin probes
or PROBE 3 for use with multiple probe systems.
All OMP40-2 settings are configured using Trigger
Logic™. This technique enables the user to
review and subsequently change probe settings
by deflecting the stylus whilst observing the LED
display.
Configurable settings are:
•
Switch-on / switch-off method
• Enhanced trigger filter setting
• Optical transmission method
• Optical power
Getting started
Three multicolour probe LEDs provide visual
indication of selected probe settings.
For example:
• Switch-on and switch-off methods
• Probe status – triggered or seated
• Battery condition
System interface
The interface conveys and processes signals
between the probe and CNC machine control.
OMM-2 with OSI / OMI-2 / OMI-2T / OMI-2H
(modulated transmission)
The OMI-2T or OMM-2 with OSI are the
recommended interfaces for use with the
OMP40-2 as they provide substantially increased
resistance to light interference whilst providing the
user greater flexibility to operate a multiple probe
system.
OMI or OMM with MI 12 (legacy transmission)
Alternative interfaces are the OMI or OMM with
the MI 12 interface unit.
MI 7 interface unit
CAUTION:
Systems using the earlier MI 7
interface in place of the MI 12 interface are not
compatible with OMP40-2.
