22 VIX IM MICROSTEPPER INDEXER DRIVE USER GUIDE
Large Motors
The largest recommended motor size is a 34-frame 3-stack. Please contact Parker if
you wish to use a larger frame motor.
Motor Connections at the Motor
Motor connections should be made directly between the drive and motor, the use of any
switching devices, such as contactors is not recommended.
In the majority of applications the drive will be used with an eight lead motor with the
windings connected in parallel or series, as shown in Figure 3-6. Motor connections will
need to be determined from the motors data sheet or Appendix B. These are normally
identified by wire colour or terminal markings, depending upon the make of the motor.
