2-12 Motor Temperature Check
Option:
Function:
Selects whether the soft starter verifies that the
motor has sufficient thermal capacity for a
successful start. The soft starter compares the
calculated motor temperature with the
temperature rise from the last motor start. The soft
starter only operates if the motor is cool enough
to start successfully.

Option:
Function:
Selects when the [Auto On] and [Hand On]
can be used to switch to hand-on mode or
auto-on mode.

3-2 Comms in Remote
Option:
Function:
Selects whether the soft starter accepts start
and stop commands from the serial communi-
cation network when in
Remote
mode.
Commands that are always enabled:
•
Force comms trip
•
Local/remote control
•

3-3 Input A Function
Option:
Function:
Selects the function of input A.
Motor set
select*
The soft starter can be configured with 2
separate sets of motor data. The primary motor
data is programmed using
parameters 1-1 to 1-16
.
The secondary motor data is programmed using
parameters 7-1 to 7-16
.
To use the secondary motor data, set this
parameter to
Motor Set Select
and close terminals
11, 16 before giving a start command. The soft
starter checks which motor data to use at a start
3-3 Input A Function
Option:
Function:
and uses that motor data for the entire start/stop
cycle.
Input trip
(N/O)
Input A can be used to trip the soft starter. When
this parameter is set to
Input Trip (N/O)
, a closed
circuit across terminals 11, 16 trips the soft
starter (
Parameters 3-5 to 3-7
).
Input trip
(N/C)
When this parameter is set to
Input Trip (N/C)
, an
open circuit across terminals 11, 16 trips the soft
starter (
parameters 3-5 to 3-7
).
Local/remote
select
Input A can be used to select between local and
remote control, instead of using the LCP keys.
When the input is open, the soft starter is in
hand-on mode and can be controlled via the LCP.
When the input is closed, the soft starter is in
remote mode. The [Hand On] and [Auto On] keys
are disabled, and the soft starter ignores any
local/remote select command from the serial
communications network.
To use Input A to select between local and
remote control, set
parameter 3-1 Local/Remote
to
LCL/RMT Anytime
.
Emergency
run
In emergency run, the soft starter continues to
run until stopped, ignoring all trips and warnings
(see
parameter 15-3 Emergency Run
for details).
Closing the circuit across terminals 11, 16
activates emergency run.
Opening the circuit ends emergency run and the
soft starter stops the motor.
Starter
disable
The soft starter can be disabled via the control
inputs. An open circuit across terminals 11, 16
disables the soft starter. The soft starter does not
respond to start commands. If running, the soft
starter allows the motor to coast to stop,
ignoring the soft stop mode set in
parameter
1-10 Stop Mode
.
When the circuit across terminals 11, 16 is
opened, the soft starter allows the motor to
coast to stop.
Jog forward
Activates jog operation in a forward direction
(operates only in Remote mode).
Jog reverse
Activates jog operation in reverse direction
(operates only in Remote mode).
