5.8.3 Wiring to Control Terminals
The control terminals are located near the LCP. The control
terminal connectors can be unplugged from the drive for
convenience when wiring, as shown in Illustration 5.10.
Either solid or flexible wire can be connected to the
control terminals. Use the following procedures to connect
or disconnect the control wires.
NOTICE
Minimize interference by keeping control wires as short
as possible and separate from high-power cables.
Connecting wire to control terminals
1. Strip 10 mm (0.4 in) of the outer plastic layer
from the end of the wire.
2. Insert the control wire into the terminal.
•
For a solid wire, push the bare wire into
the contact. See Illustration 5.13.
•
For a flexible wire, open the contact by
inserting a small screwdriver into the
slot between the terminal holes and
push the screwdriver inward. See
Illustration 5.14. Then, insert the stripped
wire into the contact, and remove the
screwdriver.
3. Pull gently on the wire to ensure that the contact
is firmly established. Loose control wiring can be
the source of equipment faults or reduced
performance.

5.8.4 Enabling Motor Operation
(Terminal 27)
A jumper wire is required between terminal 12 (or 13) and
terminal 27 for the drive to operate when using factory
default programming values.

NOTICE
The drive cannot operate without a signal on terminal
27, unless terminal 27 is reprogrammed using
parameter 5-12 Terminal 27 Digital Input.

To open the contact, insert a small screwdriver
into the slot between the terminal holes and
push the screwdriver inward.
Pull gently on the wire to free it from the control
terminal contact.
Digital input terminal 27 is designed to receive
24 V DC external interlock command.
When no interlock device is used, wire a jumper
between control terminal 12 (recommended) or
13 to terminal 27. This wire provides an internal
24 V signal on terminal 27.
When the status line at the bottom of the LCP
reads AUTO REMOTE COAST, 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.
