As suggested by others, check with Jeff.

On the other hand, If you are in a hurry, if you connected only the motor and not the sense connections, you will get a no motion error because the controller needs to see that the rotor is turning. If it doesn't see that (via the sense lines) it assumes there is a problem and stops with the error message.

If you did connect the sensor lines, try reversing them.

I am currently trying to hook my new Alfa Spid RAK rotor to my Green Heron RT21 controller.

The manual I have for the controller states that rotor terminals 1 and 2 are for Motor CW and CCW and the  Ground and Positive are on rotor terminals 3 and 4.

The manual for the rotor states that rotor terminals 1 and 2 are for motor drive and that 3 and 4 are for impulse sense.

I hooked it up according to the rotor directions and to the controller since it had been on an Alfa Spid already and it does not turn the rotor. I get a "No Motion" error on the control box. At this point I am hesitant to switch the wires around until I get some confirmation as to what is and isn't correct ( I don't want to fry anything!)


Thanks
