I recently bought a second Myford - a Super 7 this time - and originally intended to move the ML7 on but having access to two is proving very useful.
The original ML7 was converted to 3ph with an inverter which provides variable speed and I've bought a new motor for the S7 to do the same. Reading some technical detail about a Siemens Micromaster Inverter I see mention of restriction worded: "only one drive inverter is operated on one residual-current protective device".
Since my workshop is wired as a separate ring on one RCD on the distribution board (and there is no free space on the consumer unit) does this preclude me using a second VFD ?
Alternatively, can I use the existing VFD to feed both motors? The current VFD is rated at 1.5Kw. The motor on the ML7 is 0.37Kw and the new motor for the S7 is 0.75Kw?
Your collected wisdom would be most appreciated.
