Denford Triac VMC with ATC Conversion / Fix

For the coolant pump you will need to reset the connections in the motor input to delta and run it from a single phase 240v to 3 phase 220v inverter, as it will be set to star to run of 3 phase 380 - 415v atm.

The spindle drive has a connector block 1-7, 1 is the 10v supply you can leave this alone, 2 (min) is common for the 0-10v input, 3 (i/p) is the 0-10v input to control the speed. So pins 2 and 3 are the 0-10v input for the sprint board.

PS. these connections have a high voltage present on them so do not touch them, or use a grounded 0-10v signal as this will damage the sprint board. You must use a dc isolated 0-10v signal to run this drive.

Connections 5 and 7 are the run command and need to be connected together to run the drive, this is done by energising the SGR (spindle go relay). All other connections can be left alone.

Thanks. How do I do this isolation?

The CS Labs mentions this, is this the same thing?

"Another important assumption was simplicity of installation. CSMIO/IP-A does not require any external electronics for proper operation. Inputs/outputs signals are inside optically isolated, filtered, protected against short circuit, overheating etc. Of course, all I/O signals are adjusted to industry standard 24V. The device is enclosed in a compact cover, mounted on a DIN-rail, what makes that mechanical and electronic installation in a control cabinet takes less time and is even simpler. "

Mmmm, that's for the signals, not power, is it?
