2-22 SA3100 Drive Configuration and Programming
• Over Speed Limit (RPM) (Range: 10 to 20,000)
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
No Speed Feedback is the default setting.
Control Selections
• Output Rotation ( UVW, UWV )
This parameter allows you to reverse the direction of rotation of the output without
re-wiring the motor leads. Select UVW (default) or UWV. See the SA3100
Diagnostics, Troubleshooting, and Start-Up Guidelines instruction manual (S-3059)
for more information on motor orientation.
2.4.5 PMI Meter Port Selection Screen (Volts per Hertz)
The Meter Port Selection Parameter Entry screen allows you to enter specific
information about what variables are to be output on the four PMI D/A channels (the
four meter ports on the PMI motherboard. See figure 2.13.
Table 2.5 lists the values that can be displayed on the PMI meter ports. You must
enter a Minimum Value and a Maximum Value for each selection except when you
select Port Not Used. The Minimum Value is the value at which to output -10V. The
Maximum Value is the value at which to output +10V. The system software then
places the units per volt on the screen based on the Minimum/Maximum Values.
