Hi all,
Am having trouble with connecting a servo driver,
The driver has step, dir and enable + & -
My controller has step plus and step minus
Dir plus and dir minus, enable on,
I have all conected up, its enabled and locked up, but wont move,
Control signals seem to reach it, because as i move directions i see the 4.5 volts drop and rise on the pin outs
Any help appreciated
Could do with an image of your controller to see the connections or tell us which one it is so we can have a look at the pdf manual.
Normally you have 5V (or 24V)+ power connection output going from controller going to all 3 + connections on the driver in parallel.
So this one feed goes to PUL+, DIR+ & ENBL+, on ALL drives
Then the - (negative) connections go from your controller outputs.
So STEP- output to PUL-.
DIR- output to DIR-
Then ENABLE- output goes to ENBL- on ALL drives
For Example: OUT1 to ENBL- on ALL drives
OUT2 to X, PUL-
OUT3 to X, DIR-
5V+ out to ALL drives, PUL+, DIR+ & ENBL+.
This is known as active low.
It could be that your board has individual optocoupler type layout.
In these cases, usually the + connections get daisy chained to the + power feed.
