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

7. 6-15 Terminal 53 High Ref./Feedb. Value. Set
maximum speed reference on Terminal 53 at 60
Hz. (This tells the adjustable frequency drive that
the maximum voltage received on Terminal 53
(10 V) equals 60 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 that the scroll bar
on the right in the last figure of the display is at the
bottom, indicating the procedure is complete.
Figure 5.1 shows the wiring connections used to enable
this set-up.

Q3-21
•
Each terminal has specified functions it is capable
of performing.
•
Parameters associated with the terminal enable
the function.
•
For proper Adjustable frequency drive
functioning, the control terminals must be
See Table 2.3 for control terminal parameter number and
default setting. (Default setting can change based on the
