Table 4.2 Terminal Descriptions
Control terminal functions
Frequency converter functions are commanded by
receiving control input signals.
•
Programme each terminal for the function it
supports in the parameters associated with that
terminal. See Table 4.2 for terminals and
associated parameters.
•
Confirm that the control terminal is programmed
for the correct function. See chapter 5 Local
Control Panel and Programming for details on
accessing parameters and programming.
•
The default terminal programming initiates
frequency converter functioning in a typical
operational mode.

This terminal is connected to ground via an internal RC
link. Use twisted-pair cables to reduce interference
between conductors. The recommended method is shown
in Illustration 4.10.
