2M2280N High Voltage Stepper Driver

[Gary]

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.

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?

No need for the breaking resistor.

no use a star configuration for the AC.

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

Robin

[Gary]

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.

Hi Gary

It goes fine and dandy but it's running the motors hotter than I feel comfortable with. If I put a drop of suds on the motor, it boils.

I can't reduce the currrent because 3.18A is as low as it goes.

I can switch to paralell and, effectively, run less current. When you say, "A lot hotter" do you mean the motor or the driver?

You can try in in parallel and monitor the temps.
With this driver the motors will run hot, but they shoud be ok.
