Hi, I am using a UMI 7774 motion interface to control a Parker Servo drive (AR-08SE). The Servo Drive requires a differential input for the step and direction signals so I followed this wiring diagram. (http://www.parkermotion.com/scripts/support_faq.asp?rowid=AAAH0UAAKAABvpjAAD&count=1&random_number=1...) I am using MAX to operate the system but I can not get the servo motor to operate. It has holding torque but will not turn when I command it to. I get a "motor off (axis is killed)" and "following error occured" message. Am I missing something in the software setup? Or is it a wiring issue?
This could be a wiring issue (e. g. interchanged encoder phases), but there are also other potential reasons. Please refer to this document in the NI knowledge base for further troubleshooting information.
