LED indicates probe status
Lit when probe is at rest or interface is inhibited.
Off indicates probe stylus is deflected, or power Is off.
Audible indicator
A tone is emitted each time the probe changes state.
From rest to deflected or deflected to rest.
The MI 5 interface unit is part of a hard wired or inductive transmission probe system.
It is used with CNC machine tools for workpiece set up and inspection.
The MI 5 converts probe signals into an acceptable form for the CNC machine control.
MI 5 operation
The MI 5 interface monitors probe status. When the probe triggers or reseats, the output relays change state, and the audible indicator sounds.
The front panel LED (Light Emitting Diode) is lit up when the stylus is seated, and is off when the stylus is deflected, or the power is off.
The output signal is simultaneously transmitted to the CNC control through the solid state relay
(SSR) output(s).
As the probe moves away from the workpiece, the audible indicator emits a second 'bleep', and the LED lights up, indicating that the stylus has reseated, and the probe is available for the next move in the measuring cycle.
The input power supply and SSR outputs are fuse protected by 200mA and 63mA fuses respectively.
To gain access to the fuses, remove the four cover screws and cover.
Inhibit / enable function
The MI 5 output may be held in the probe at rest state.
This can be automatically controlled by an M code from the CNC machine control.
Power supply
The interface unit can draw its power from the CNC machine nominal 24V dc supply. Its input voltage range is 18V dc to 30V dc and it presents a load of up to 200mA. It can alternatively be powered from a Renishaw PSU3 Power Supply Unit.
Environment
The MI 5 interface is specified for storage over –10° to 70°C (14° to 158°F) and operation over 0° to 50°C
(32° to 122°F) ambient temperature range.
