    UD53 fitted. Initial setting up By default, the UD53 is configured for operation with a resolver having a 3:1 turns ratio. If the resolver to be used has a turns ratio of 2:1, set parameter 16.10 Resolver turns ratio select at 1.
  • Page 15 Refer to Autotune in Chapter 3 Setting Up the Drive in the Unidrive User Guide, or to parameter 5.12 in the Unidrive Advanced User Guide. If the Drive trips while Autotune is being performed, see the Note above. UD53 User Guide Issue code: 53nu3...

  • Page 16: Change In Feedback Resolution With Change Of Maximum Speed

    Change in feedback resolution with change of maximum speed The resolver feedback signals are sampled by the UD53 at a resolution that depends on the maximum speed of the Drive. (This is determined by the value of 1.06 Maximum speed, and when 1.08 Negative minimum speed select is set at 1, it can also be determined by 1.07 Maximum reverse speed.)
