Secondary Motor Set
The EMX4i can be programmed with two separate starting and stopping profiles.
This allows the soft starter to control the motor in two 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 two different conditions
(such as loaded and unloaded conveyors).
The secondary motor set can also be used for duty/standby applications.
NOTE
For duty/standby applications, set parameter 6Q
Motor Overtemperature
to
Log Only and install temperature protection for each motor.
To use the secondary motor set, a programmable input must be set to 'Motor Set
Select' and the input must be closed when a start command is given (refer to 7A
Input A Function
and 7E
Input B Function
). The EMX4i checks which motor set to
use at a start, and will use that motor set for the entire start/stop cycle.
