2.5.6 Control Terminal Functions
Frequency converter functions are commanded by
receiving control input signals.
•
Each terminal must be programmed for the
function it will be supporting in the parameters
associated with that terminal. See
and
for terminals and
associated parameters.
•
It is important to confirm that the control
terminal is programmed for the correct function.
See
for details on accessing
parameters and programming.
•
The default terminal programming is intended to
initiate frequency converter functioning in a
typical operational mode
2.5.6.1 Terminal 53 and 54 Switches
•
Analog input terminals 53 and 54 can select
either voltage (-10 to 10 V) or current (0/4-20 mA)
input signals
•
Remove power to the frequency converter before
changing switch positions
•
Set switches A53 and A54 to select the signal
type. U selects voltage, I selects current
•
The switches are accessible when the LCP has
been removed (see
).
NOTE
Some option cards available for the unit may cover these
switches and must be removed to change switch settings.
Always remove power to the unit before removing option
cards.
•
Terminal 53 default is for a speed reference signal
in open loop set in
16-61 Terminal 53 Switch
Setting
•
Terminal 54 default is for a feedback signal in
closed loop set in
