Hey Guys, virgin poster here. We have a Mazak VCN 510C with a Renishaw OMP40/OMI. It has been a few years since the Renishaw probe was last used. New batteries were installed. Here is the problem: the machine will not do a tool change if the tool is defined as a "touch sensor". Sometimes it will change it from the atc to the spindle but not visa versa. It goes into position to change tools but just sits there and times out with a 363 - hyraulic pump time over. Here's the kicker, if the probe is not defined as a "touch sensor" it will change back and forth from tool changer to spindle just fine. For some reason it seems like the machine does not like "touch sensors". Could there be a parameter issue here? FYI- Renishaw system was installed at the factory so we have no software with it. Thanks in advance.

Baader Kevin, did you find a solution for your problem?
I'm having the same problem with Mazak Nexus 410A-II with Mazatrol control. I'm attempting to get a Renishaw RMI receiver and a RMP600 probe running for the first time and I've encountered the same issues you describe. As a 'Touch Sensor', the Z axis will move to the tool change position and the hydraulic unit will run but the tool change does not operate.
Additionally, a '230 illegal MMS unit' alarm is triggered when the touch sensor is manually removed from the spindle.
Any insight would be invaluable.

Solved it.
The probe was provided with a shank switch and was configured to turn on and off with the shank switch. It seems that the tool change operation would not complete as long as the probe was powered on yet the probe would not power off until it was out of the shank. Re configuring the probe to power on/off via radio signal solved the problem and tool change will now complete as required.
