Applications and risks
Units from the LV7000 series are designed for the speed control of three-phase standard induction motors,
taking the technical motor and unit specifications into consideration.
In addition, LV7000-3 units may control also synchronous motors with permanent magnets.
The integration of the unit into plants or drive systems is not within the sphere of product responsibility of
Converteam.
This concerns the functions and operating safety of the entire system, as well as repercussions, if any, on
other facilities and systems.
The user of the unit is hence responsible for ensuring that the applicable technical standards and rules,
statutory requirements and codes in force at the place of installation are adhered to in conjunction with the
engineering and installation of the overall system.
The following information is to help to assess the risks related to the use of the unit. It is the user’s
responsibility to take any measures suitable to address these risks.
•
Under incorrect or unwanted conditions, the motor can work
- at an incorrect speed
- at a high overspeed
- and / or in the wrong direction.
•
An excessive supply voltage drop or an interruption of the supply voltage causes an immediate shutdown.
The motor connected is then no longer controlled by the converter.
The user of the unit must take suitable measures in order to master these cases (such as mechanical
protection devices, additional peripheral electrical monitoring and safety equipment, redundant configuration)
in order to avoid personal injury and damage to property, as well as to minimize interference with the ongoing
process based on a risk analysis to be carried out by the user.
