9.13 Inside Delta Operation
When connecting in inside delta, enter the value of the FLC in parameter 1-2 Motor Full Load Current. The soft starter automatically
detects whether the motor is connected in-line or inside delta and calculates the correct inside delta current level.
Adaptive control, jog, brake, and PowerThrough functions are not supported with inside delta (6-wire) operation. If these functions
are programmed when the soft starter is connected inside delta, the behavior is given as below.
The soft starter performs a constant current start.
The soft starter performs a TVR soft stop if parameter 2-10 Stop Time is >0 s. If parameter 2-10 Stop Time is
set to 0 s, the soft starter performs a coast to stop.
The soft starter issues a warning with the error message Unsupported option.
The soft starter performs a coast to stop.
The soft starter performs a coast to stop.
The soft starter trips with the error message Lx-Tx Shorted.
N O T I C E
When connected in inside delta, the soft starter does not detect phase loss on T2 during run.
N O T I C E
If the soft starter is not correctly detecting the motor connection, use parameter 20-6 Motor Connection.
9.14 Secondary Motor Set
The soft starter can be programmed with 2 separate starting and stopping profiles. This allows the soft starter to control the motor
in 2 different starting and stopping configurations. The secondary motor set is ideal for dual winding (Dahlander) motors, multi-
motor applications, or situations where the motor may start in 2 different conditions (such as loaded and unloaded conveyors). The
secondary motor set can also be used for duty/standby applications.
