Omron LX AC Drives

AC electric drives Omron series LX designed to work with asynchronous and synchronous electric motors of elevator equipment. To ensure safe and comfortable use of this type of equipment, special algorithms and installations are built in to regulate the speed and position of the cabin. They are able to save and use for movement sequences of actions for servicing elevators of buildings with up to 40 floors. Direct (from the front panel) and remote (via PC) programming and control of operating parameters are provided.

The tools used to control the motor can use both sensory and sensorless signal processing. The starting torque reaches 2 times the nominal values even at zero frequency. To meet the high standards of safety, a wide range of protective measures has been applied, and a backup power supply has been built in to fulfill the evacuation plan. Accounting for time and calendar days makes it possible to debug the operational nuances of lifting equipment.
