Illustration 5.4 Analog Reference 6-10 Terminal 53 Low Voltage
5.
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.)
Illustration 5.5 Analog Reference 6-11 Terminal 53 High Voltage
6.
6-14 Terminal 53 Low Ref./Feedb. Value. Set
minimum speed reference on Terminal 53 at 6
Hz. (This tells the frequency converter that the
minimum voltage received on Terminal 53 (0 V)
equals 6 Hz output.)
Illustration 5.6 Analog Reference 6-14 Terminal 53 Low Ref./
Feedb. Value
7.
6-15 Terminal 53 High Ref./Feedb. Value. Set
maximum speed reference on Terminal 53 at 60
Hz. (This tells the frequency converter that the
maximum voltage received on Terminal 53 (10 V)
equals 60 Hz output.)
Illustration 5.7 Analog Reference 6-15 Terminal 53 High Ref./
Feedb. Value
With an external device providing a 0-10 V 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 5.8 shows the wiring connections used to
enable this set up.

Terminal Programming
Examples
Control terminals can be programmed.
•
Each terminal has specified functions it is capable
of performing
•
Parameters associated with the terminal enable
the function
See Table 2.6 for control terminal parameter number and
default setting. (Default setting can change based on the
selection in 0-03 Regional Settings.)
The following example shows accessing Terminal 18 to see
the default setting.
