Hi Gary
Just found the 2M2280N High Voltage Stepper Driver on your website.
Looks like God's gift to his chosen few at a very reasonable price
Can I really plug them in to the mains without transformers, get big speeds and not worry about a mains surge toasting them?
Standing by for your reply, dosh in hand, pencil me in for 3
One more question. What to do with the error output? It's open collector so presume link all 3 together and use it to kill all the En inputs so if one stops they all stop.

Its a brand new product, that replaces the old PM2278.
It is a lot better than to old driver with better anti resonance circuitry and it auto tunes to the motor as well.
Also you get very smooth motion as well.
Also has over voltage protection as well.
Will have to look into the error outputs, this is a feature ive not looked into yet.
Also sold out so you are looking at about 7-10 days i think.

Thanks for the order.
For some reason, this driver has become very popular, but as soon as stock arrives, i will dispatch your order.
The driver is protected, and has error indicator LEDS, so if you get a voltage spike, it will just trip out and it will tell you what the cause is, by looking at the led's.
I think the over voltage protection kicks in at 253V, so if you are living in an area that is prone to high voltage spikes, then you may need to get some surge protection, or you may get the driver going into error, half way through a job, but at least you have the error output to tell mach that motion has stopped.Visit Us: www.automationshop.co.uk

Hi Gary
Do I fit the braking resistors? If so what Ohms and what Watts?
Is it okay to daisy chain the mains on to them?
Much ta

Me again
Parallel or series? Would it make any noticeable difference to the top speed or just generate unnecessary heat?

Parallel will give you more speed / mechanical power, but will also run a lot hotter.
My suggestion is to try it in series and if it works for you leave it there.
If you find you need more speed, connect it in parallel.
Dont forget to set the correct currents.
If it is the FL86STH156 or SY85STH156 it is 3A in series and 6A in parallel.

Gary has supplied us with some of these drives today and we have had one running. Very impressive
I think you will be very pleased with your purchase
