Table 4.3 Terminal Description
Additional terminals:
•
Two form C relay outputs. Location of the
outputs depends on adjustable frequency drive
configuration.
•
Terminals located on built-in optional equipment.
See the manual provided with the equipment
option.
4.8.2 Wiring to Control Terminals
Control terminal connectors can be unplugged from the
adjustable frequency drive for ease of installation, as
shown in
NOTICE!
Keep control wires as short as possible and separate
from high power cables to minimize interference.
1.
Open the contact by inserting a small screwdriver
into the slot above the contact and push the
screwdriver slightly upwards.

2.
Insert the bared control wire into the contact.
3.
Remove the screwdriver 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
chapter 8.5 Cable Specifications
for control terminal
wiring sizes and
chapter 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 adjustable frequency drive 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 an internal 24 V
signal on terminal 27.
•
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 adjustable frequency drive 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!
Disconnect power to the adjustable frequency drive
before changing switch positions.
