No Speed Feedback

If you select No Speed Feedback, which is the default, you do not have to enter Motor Base Speed,

Overspeed Trip Point, or Tach Volts at Over Speed Trip, however, you can select a resolver for

positioning purposes.

Note that if you select No Speed Feedback, the PMI Processor will not perform the Tach Loss and
Over Speed Diagnostics. You must provide an independent method of detecting motor overspeed.
Note also that automatic field weakening will be disabled if you select No Speed Feedback. Refer to
register 100/1 00, bit 11 for more information. Note that when a speed feedback device is used,
overspeed detection is active during auto-tuning.
