2. Insert the bared control wire into the contact.
3. Remove the screw driver to fasten the control
wire into the contact.
4. Ensure the contact is firmly established and not
loose. Loose control wiring can be the source of
equipment faults or less than optimal operation.
See 8.5 Cable Specifications for control terminal wiring sizes
and 6 Application Set-up Examples for typical control wiring
connections.
4.8.3 Enabling Motor Operation (Terminal
27)
A jumper wire may be required between terminal 12 (or
13) and terminal 27 for the frequency converter to operate
when using factory default programming values.
•
Digital input terminal 27 is designed to receive an
24 V DC external interlock command. In many
applications, the user wires an external interlock
device to terminal 27
•
When no interlock device is used, wire a jumper
between control terminal 12 (recommended) or
13 to terminal 27. This provides in internal 24 V
signal on terminal 27
•
No signal present prevents the unit from
operating
•
When the status line at the bottom of the LCP
reads AUTO REMOTE COAST, this indicates that
the unit is ready to operate but is missing an
input signal on terminal 27.
•
When factory installed optional equipment is
wired to terminal 27, do not remove that wiring
NOTICE
The frequency converter cannot operate without a signal
on terminal 27 unless terminal 27 is re-programmed.
4.8.4 Voltage/Current Input Selection
(Switches)
The analog input terminals 53 and 54 allow setting of
input signal to voltage (0-10 V) or current (0/4-20 mA).
Default parameter settings:
•
Terminal 53: speed reference signal in open loop
(see 16-61 Terminal 53 Switch Setting).
•
Terminal 54: feedback signal in closed loop (see
16-63 Terminal 54 Switch Setting).
NOTICE
Remove power to the frequency converter
before changing switch positions.
1. Remove the local control panel (see
Illustration 4.13).
2. Remove any optional equipment covering the
switches.
3. Set switches A53 and A54 to select the signal
type. U selects voltage, I selects current.
