2.3.3 Feedback Data Screen (Vector with Constant Power)
The Feedback Data Parameter Entry Screen allows you to enter specific information
about the resolver connected to the Resolver and Drive I/O module on the PMI. See
figure 2.7.
• Over Speed Limit (RPM) (Range: 10 to 10,000)
This value is used to determine the maximum safe output frequency of the drive.
There is no default value. Over Speed Limit should generally be equal to or less
than the motor maximum safe speed or the driven equipment maximum safe speed,
whichever is lower. If a value less than Rated Full Load Speed of the motor is
entered, a warning will be generated.
• Speed Feedback Type
You must select Resolver. The No Speed Feedback option is not allowed for vector
regulators.
Resolver Data
• Resolver Type (x1, x2, x5)
Select the resolver type from the three choices: x1, x2, or x5. The “None” option is
not allowed for vector regulators. The resolver selected must be able to operate at
the Over Speed Limit of the motor.
• Resolution
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:
