Secondary Motor Set - Danfoss VLT MCD 600 Operating Manual

Operating Guide | VLT® Soft Starter MCD 600
Adaptive control start The soft starter performs a constant current start.
Adaptive control stop The soft starter performs a TVR soft stop if parameter 2-10 Stop Times is >0 s. If parameter 2-10 Stop Times is
set to 0 s, the soft starter performs a coast to stop.
Jog The soft starter issues a warning with the error message Unsupported option.
DC brake The soft starter performs a coast to stop.
Soft brake The soft starter performs a coast to stop.
PowerThrough The soft starter trips with the error message Lx-Tx Shorted.
When connected in inside delta, the soft starter does not detect phase loss on T2 during run.
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.
For duty/standby applications, set parameter 6-17 Motor Overtemperature to Log Only and install temperature protection for
each motor.
To use the secondary motor set, set a programmable input to Motor Set Select. The input must be closed when a start command is
given (see parameter 7-1 Input A Function and parameter 7-5 Input B Function. The soft starter checks which motor set to use at start and
uses that motor set for the entire start/stop cycle.
The soft starter uses the secondary motor settings to control a start when instructed via a programmable input (see parameter 7-1 Input
A Function and parameter 7-5 Input B Function).
The motor thermal model is less accurate if the soft starter controls 2 separate motors.
