Products Detail

Features

Suitable for driving control of permanent magnet synchronous motors and asynchronous motors, with multiple rotary encoder interfaces.

Equipped with motor parameter self-tuning function, it can perform static tuning or complete tuning.

Support multi segment speed and analog speed setting.

Flexible start curve processing, multi segment S curve setting, and 4-level acceleration and deceleration time setting can ensure good elevator operation comfort.

It has a simple and practical battery operation function, and can complete power outage self rescue with a 48V power input.

It has various elevator specific functions such as enabling detection, holding brake contactor control, output contactor control, forced deceleration judgment, overspeed protection, speed deviation detection, early door opening, contact adhesion detection, motor overheating detection, starting pre torque compensation, etc., making elevator control simple and feasible.

The unique single key design of the control panel makes complex keyboard operations easy and effortless, and can be connected to any position through the RJ45 port, making elevator debugging convenient and simple. The parameter copying unit is easy to use and facilitates batch debugging.

The built-in DC reactor and braking unit improve the output power factor of the system and reduce the cost of external components in the electrical system.

The full series of independent air duct design, professional lightning protection design, specialized processing and production platform, and advanced process control ensure the quality of the LC520 elevator specific frequency converter.

The LC520 elevator specific frequency converter is equipped with a complete lightning protection design, greatly improving the reliability of the system. In addition, the LC520 elevator specific frequency converter has strong anti-interference ability and meets strict EMC testing standards.
