Gents Ladies.. Got the Kiti allmost up and running..
Could some good soul shed some light on this problem.. When S1000 command is issued.. the rotation on the VFD ( Old S series analog Fanuc Spindle 6S) displays 735.. means that there is a 1.25 difference .. It's linear.. any ideas?

Regards
Peetr

Is this a geared head or belt drive? Have you checked the actual spindle speed? Something like a 6000 rpm motor running a 7500rpm spindle maybe?

The motor is up to 8k.. didnt measure the pulleys but my 2 cents is that it's 1:1

There are lots of ways a machine builder can manage spindle control. I'd start by verifying the settings of parameters 539 through 543.

There may also be PMC parameters used for spindle control. Often used to configure the ladder to suit the configuration of the machine. Those will be machine builder determined so you may need to contact your builder if you do not documentation for your ladder or PMC parameters.

I looked in my S series documentation and it shows a maximum motor speed for a 6S as 6000 rpm. You may have something newer than my manuals cover.

What is the back story on the machine? Is this a replacement drive or motor or something? Did you lose the parameter memory in the past?

it was a scrap machine we bought for retrofit, but the 0M came up after battery replacement. it was missing the spindle drive board.. bought one on flee bay.. but didn;t know back then bout the ROM versions./. ( I supposed that they are all the same and only the params change based on the spindle size.. ) I was wrong .

Nice!

I saw your other thread about missing PMC (DGNOS 300+) parameters. Did you get those sorted out?
