Connecting input signals on NI ISM-7411 Ethernet stepper

Hello,

I'm using 7411 and made it work with configuration utility and LV basic example(Axis Straight Line Move - Ethernet Stepper).

And now I'm trying to use enable input(EN) to stop and move the motor.

I followed connection from the manual like below and enabled using EN input on configuration utility.

I tried several ways like connecting EN+- to SMPS +- and cut off power from SMPS or connecting DIO(5V) to EN+-, setting EN Input as Enable motor when closed/open(both ways)

But I still cannot stop the motor with EN input.

What should I try? Please give me some comment with connecting input and writing / reading properties / methods.

Thanks.
