Configuring the UDC Module, Regulator Type, and Parameters 2-17
• External Speed for Constant Power
This option allows you to supply an external speed reference (RPM) to the drive.
The drive uses this speed feedback reference from the UDC in place of the PMI
speed feedback signal to reduce the magnetizing current when motor is operating in
the constant power region.
2.4.4 Feedback Data Screen (Vector)
The Feedback Data parameter screen allows you to enter specific information about
the resolver used with the motor, the motor overspeed limit, and the direction of motor
rotation. See figure 2.10.

• Over Speed Limit (RPM) (Range: 10 to 10000)
The over speed limit is used to select the speed at which the over speed fault
should be generated by the PMI. Enter the value in RPM. A typical value is 110% of
gear-in speed.
Resolver Data
• Resolver Type (x1 or x2)
Select x1 (default) or x2.
• Resolution (12-bit or 14-bit)
This value is used to configure the PMI’s resolver-to-digital converter for either
12-bit or 14-bit conversion of the resolver data. The 12- or 14-bit modes are
designed to be used with the following resolvers:
