Key Features

MVE soft starters offer several special functions to ensure ease of use and to provide optimal motor control in all environments
and applications.
Customisable Protection
The MVE offers comprehensive protection to ensure safe operation of the motor and soft starter. The protection characteristics
can be customised extensively to match the exact requirements of the installation.
4 Protection Settings
Use

Example:
Use parameter 4C

16 Protection Action

activates. Each protection can be set to trip the starter, activate a warning flag, or be ignored. All protection
activations are recorded in the event log, regardless of the protection class setting.
Example:
Use parameter 16C
The default response is trip.
NOTE
MVE soft starters have built-in trip points to ensure operation remains within the soft starter's capability. These
internal trips cannot be overridden. Certain faults within the MVE will also prevent the soft starter from operating.
Troubleshooting
Refer to
Advanced Thermal Modelling
Intelligent thermal modelling allows the soft starter to predict whether the motor can successfully complete a start. The MVE uses
information from previous starts to calculate the motor's available thermal capacity, and will only permit a start which is predicted
to succeed.
This feature can be enabled or disabled using parameter 4N
Comprehensive Event and Trip Logging
The MVE has a 99-place event log to record information on soft starter operation. A separate trip log stores detailed information
about the last eight trips. Refer to
download the software, visit www.aucom.com.
Informative Feedback Screens
A digital display screen allows the MVE to display important information clearly. Comprehensive metering information, details of
starter status and last start performance allow easy monitoring of the starter's performance at all times.
Dual Parameter Set
The MVE can be programmed with two separate sets of operating parameters. This allows the soft starter to control the motor in
two different starting and stopping configurations.
The secondary motor settings (parameter groups 9 and 10) are ideal for conventional (squirrel-cage) motors which may start in
two different conditions (such as loaded and unloaded conveyors).
NOTE
The MVE is not suitable for controlling two separate motors. The secondary parameter set should only be used for a
secondary configuration of the primary motor.
The MVE will use the secondary motor settings to control a start when instructed via a programmable input (refer to parameters
6A and 6F,
Input A or B Function
Fibre-Optics
The MVE uses two-line fibre-optic connections between the low voltage and high voltage zones for electrical isolation. This
fibre-optic link simplifies installation of chassis mount MVE starters into custom panels.
