6. 3-03 Maximum Reference. Set maximum internal
adjustable frequency drive reference to 60 Hz.
(This sets the maximum adjustable frequency
drive speed at 60 Hz. Note that 50/60 Hz is a
regional variation).

8. 6-11 Terminal 53 High Voltage. Set maximum
external voltage reference on terminal 53 at 10 V.
(This sets the maximum input signal at 10 V).

9. 6-14 Terminal 53 Low Ref./Feedb. Value. Set
minimum speed reference on terminal 53 at 20
Hz. (This tells the adjustable frequency drive that
the minimum voltage received on terminal 53 (0
V) equals 20 Hz output).

With an external device providing a 0–10 V control signal
connected to adjustable frequency drive terminal 53, the
system is now ready for operation.
NOTE!
The scroll bar on the right in the last figure of the display
is at the bottom, indicating the procedure is complete.
Figure 5.10 shows the wiring connections used to enable
this set-up.
