11 RTD/PT100 (Reserved)
This parameter group is reserved for future use.
12 Slip-Ring Motors
These parameters allow the soft starter to be configured for use with a slip-ring motor.
12A – Motor 1 Ramp
Options: Single Ramp (default)
Dual Ramp
Description: Selects whether to use a single or dual current ramp profile for soft starting. Set to single ramp for non-slip
ring induction motors, or dual ramp for slip-ring induction motors.
12B – Motor 2 Ramp
Options: Single Ramp (default)
Dual Ramp
Description: Selects whether to use a single or dual current ramp profile for soft starting. Set to single ramp for non-slip
ring induction motors, or dual ramp for slip-ring induction motors.
Parameter 12B selects the ramp configuration for the secondary motor.
12C – Changeover Time
Range: 100 - 500 (milliseconds)
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%
Description: Sets the level of conduction after the rotor resistance contactor 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
Description: Sets the access code to control access to restricted sections of the menus.
Use 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)
Read Only
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.
