RPM is running much slower then inputed rpm
VMC40 w/88HS control
Last night I used the RI command to clear the machines memory of everything, I then sent over a program. I'm 99.9% sure I was warming the spindle up after I sent the program over, but my compressor died on me so I called it quits.
Today I power up the machine, CS, and give it a S1000M3 to start warming up the spindle, but the spindle isn't running anywhere near 1,000rpm, it cant be spinning more then 100rpm. I program 10,000rpm and it looks as if its running around 1,000 rpm. I powered down the machine and powered it back up and it didn't help. Any ideas?
Re: RPM is running much slower then inputed rpm
I've been playing with an AC servo which I plan to use. I've never touched 1 before so I'm doing a lot of bench testing.
Anyway. I was asking it to go 400rpm on a test but it was only reaching 200rpm itself.
There was a peramiter called 'speed command gain'. It was defalt at 100. I changed the setting to 300 and it is now spot on.
Have a look and see if you have any paramiters like this (might also be listed as analog). You may have reset this to it's default setting.
