Hi guys,
I've got a Mazak SQT15MS T32-3. When I turned it on today the keys at the operation panel were not working and a few minutes later Alarm 15 "System Malfunction" came up on screen. I restarted several times but the same result. I looked in the electrical cabinet and when it's started initially all the drives LED's appear correct (i.e.: X/B Drive :Flashes between d1 & d4 . Z Drive:d2. Sub Spindle Drive: r0 . Main spindle Drive r0.) but after a few minutes the main spindle drive LEDs go blank, showing nothing (that's when the Alarm comes up on screen).
In the Alarm manual it says the following :
Alarm 015 System Malfunction.

Cause: An error occurred in data transmission between MCP and the Amp when the power is turned on.

Action: Check Amplifier for :
Improper connections.
Improper power connections.

So what I'm wondering is what is the MCP and what Amp are they on about ?
Any advice please ? Is this a sign of some problem anyone is familiar with ? What's my best course of action ?
