Additional terminals:
•
2 form C relay outputs. The location of the
outputs depends on the frequency converter
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
frequency converter for ease of installation, as shown in
Illustration 4.25.

NOTICE
Keep control wires as short as possible and separate
from high power cables to minimise interference.

4.8.3 Enabling Motor Operation (Terminal
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.

•
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
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 setting:
•
•
NOTICE
Disconnect power to the frequency converter before
changing switch positions.
Open the contact by inserting a small screwdriver
into the slot above the contact and push the
screwdriver slightly upwards.
Insert the bare control wire into the contact.
Remove the screwdriver to fasten the control wire
into the contact.
Ensure that the contact is firmly established and
not loose. Loose control wiring can be the source
of equipment faults or reduced performance.
27)
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 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.
(Switches)
Terminal 53: Speed reference signal in open loop
(see parameter 16-61 Terminal 53 Switch Setting).
Terminal 54: Feedback signal in closed loop (see
parameter 16-63 Terminal 54 Switch Setting).
