Description:
Sets the delay between the rotor resistance relay closing and the low resistance current ramp
starting. Set so that the contactor has enough time to close, but the motor does not slow
down.
Parameter 12C only applies if parameter 12A or 12B is set to 'Dual Ramp', and an output
relay is set to 'Changeover Contactor'.
12D – Slip-Ring Retard
Range:
10% - 90%
Default: 50%
Description:
Sets the level of conduction while the rotor resistor closes, as a percentage of full conduction.
Set so that no current pulse occurs, but the motor retains enough speed to start correctly.
15 Advanced
15A – Access Code
Range:
0000 - 9999
Default: 0000
Description:
Sets the access code to control access to restricted sections of the menus.
Use the and buttons to select which digit to alter and use the
and
buttons to
change the value. After the last digit is set press STORE.
NOTE
In the event of a lost access code, contact your supplier for master access code that allows you to
re-program a new access code.
15B – Adjustment Lock
Options: Read

Write
(Default)
Allows users to alter parameter values in the Programming Menu.
Read Only
Prevents users altering parameter values in the Programming Menu.
Parameter values can still be viewed.
Description:
Selects whether the Controller will allow parameters to be changed via the Programming
Menu.
15C – Emergency Run
Options:
Disable (Default)
Enable
Description:
Selects whether the soft starter will permit emergency run operation. In emergency run, the
soft starter will start (if not already running) and continue to operate until emergency run
ends, ignoring stop commands and trips.
Emergency run is controlled using a programmable input.
16 Protection Action
These parameters define how the soft starter will respond to different protection events. The soft starter can trip, issue
a warning, or ignore different protection events as required. All protection events are written to the event log. The
default action for all protections is to trip the soft starter.
CAUTION
Defeating the protection may compromise the starter and motor, and should only be done in the case of
emergency.
16A~16W – Protection Actions
