About Frequency Converter P...
5. 3-03 Maximum Reference. Set maximum internal
frequency converter reference to 60Hz. (This sets
the maximum frequency converter speed at 60Hz.
Note that 50/60Hz is a regional variation.)

6. 6-10 Terminal 53 Low Voltage. Set minimum
external voltage reference on Terminal 53 at 0V.
(This sets the minimum input signal at 0V.)
Illustration 5.6
7. 6-11 Terminal 53 High Voltage. Set maximum
external voltage reference on Terminal 53 at 10V.
(This sets the maximum input signal at 10V.)
Illustration 5.7
8. 6-14 Terminal 53 Low Ref./Feedb. Value. Set
minimum speed reference on Terminal 53 at
20Hz. (This tells the frequency converter that the
minimum voltage received on Terminal 53 (0V)
equals 20Hz output.)

With an external device providing a 0-10V control signal
connected to frequency converter terminal 53, the system
is now ready for operation. Note that the scroll bar on the
right in the last illustration of the display is at the bottom,
indicating the procedure is complete.
Illustration 5.10 shows the wiring connections used to
