Gemini GV Hardware Installation Guide
Motor Resolver
Resolvers on Compumotor motors are aligned at the factory. Ordinarily, no further
alignment is necessary. However, if you suspect that the resolver has been altered
and is out of alignment, you can follow the alignment procedure in Aligning the
Resolver, located in Chapter 4 Special Features.
Mechanical System
Shaft Coupler
Verify that the shaft coupler is not slipping during acceleration or deceleration. We
recommend bellows or disk style couplers for servo applications. Helical couplers
are inadequate, and are not recommended.
Mechanical Transmission
Verify that your mechanical system functions properly, and is not jammed.
Motion Problems
If problems occur during motion, check these possible causes:
•
Motor Sizing (ensure that the motor has enough torque to perform the move)
•
Excessive Acceleration or Deceleration
•
Excessive Velocity
Electrical Noise
Electrical noise on input or output lines can cause stop or kill inputs to activate
unexpectedly. See Appendix C: Regulatory Compliance for installation guidelines
on reducing electrical noise.
Software/Motion Program Problems
Check to see that your motion programs are functioning properly, and are not
causing unexpected problems.
