Connecting third party motor to p7000 tools

[mark514]

Hi,

I have a vexta PK245-011AA stepper motor and I'm trying to control it with a P70350 drive via P7000 tools software. When I enter the specification of the motor in the "Stepper Motor/Motor File Editor" menu and select my motor configuration (see attached file), the drive becomes disabled, with status "Open motor phase" and the led is blinking red. I tried lowering the current, but the drive is still disable.

All the dip switches of the drive are turned off. The cables of the motor are wired as per the operating manual diagram (there are 6 wires, I only wire 4 wires as follow: A=black, A_bar=green, B=red, B_bar=blue).

Any ideas what the problem could be?

Thank you,

Marc

Found the problem: it seems that the wire diagrams was wrong. After checking the resistance between the wires I founded that the 2 sets of wires per  phase were Blue-White-Green and Red-Black-Orange, with White and Black being center tap, thanks to this NI page

Now motor works properly!
