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.

5.3 Control 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 2.4 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.
