Configuring the UDC Module, Regulator Type, and Parameters 2-11
• 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:
For the most accurate velocity control, always select the resolver (x1 or x2) whose
maximum speed is closest to, and greater than, the maximum speed for your
application. Refer to the SA500 Power Modules instruction manual (S-3018) for
more information regarding the PMI’s resolver-to-digital converter and the
supported resolvers.
Control Selections
• Output Rotation
This parameter allows you to reverse the direction of rotation of the output without
re-wiring the motor leads. Select UVW (default) or UWV.
• Position/Speed Loop
This parameter allows you to choose whether a position/speed loop in the PMI is to
be used or not. If it is, select enable and also the type of position feedback: resolver
feedback, analog input, or an external variable. The default is that the
position/speed loop will not be used.
• Position Feedback Selection
If the position/speed loop is selected, select the type of position feedback: resolver
feedback, analog input, or an external variable. The default is resolver feedback.
Resolver feedback is scaled automatically. Analog input data is scaled so that 2048
equals one mechanical revolution of the positioning device. External variable data is
scaled so that 4095 equals one mechanical revolution of the positioning device.
