spindle issues
« on: June 15, 2013, 04:48:21 AM »
Have just setup my new parker ssd650 inveter drive,

1st issue -
When I input a m3s2500 the 0-10v output is 9.90v (not a prob for max spd), but anything less than s2340 then the 0-10v reads 0v and the obv the spindle wont turn, I have tried all manor of setups in motor tuning but to no luck.

I have how ever connected the 0-10v output to a pot then to the inverter and when 0-10v is at max I can control the spindle spd from o-s2500 via the pot, but obv mach3 spindle dro only reads s2500. Any thoughts as to why I cant get any less than s2340 through mach?

2nd issues -
In order to use 0-10v input on the inverter, the inverter still requires a signal to turn the spindle on, but with this inverter that is by the means of a 24v signal, is there any way I can use the spindle on signal from my sp4dc board to activate a switch connected to a 24v circuit?

Any thoughts greatly appreciated

You may need to go into Config, spindle pulleys and setup up the ratios.

Toget it to turn on and off you normally need to use an output so that the M3 turns it on and the M5 turns it off.

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

Ah didnt think of the pulley setup, my current setup is
min - 0
max - 2600
ratio - 1

Think maybe it should be
min - 0
max - 2600
ration - 10:1 - so min would be 10% of the max 260

Regards to the 24v switching I've found this ssr switching board, controlled by an output signal.

10 to 1 works well as a starting point when setting up an analog spindle.

That board should do the trick nicely.
