It’s so hard to face electricity fail while you are in elevator "alone", but which is harder if you were suffering from Claustrophobia, for such like this cases our solution created out, With CE, ISO9001 Certificate.

Special automatic inverter designed for elevator.
It can not only control the traditional traction machine with gear, but also new kind ones without gear.
Its outstanding performance can match with elevator control logic.
And can ensure the safety and comfort ability.

Features

1. Compatible with asynchronous and synchronous motor
2. Torque compensation without load sensor: (With sin/cos encoder), can control the synchronous traction machine without gear to smoothly start.
3. Torque compensation with load sensor: avoid reverse slipping when starts.
4. Identify initial angle of pole at static: For permanent magnet synchronous motor, it can autotune at static status (with SIN/COS encoder), and do not need to disconnect the load.
5. S-curve: make sure to be comfort when elevator accelerates, decelerates and stops.
6. Optimize speed loop: For high  dynamic response, the speed loop adopts variable proportional and integral gains.
7. Emergency operation function: Leveling the nearest floor automatically, also can use for long time "depended on the battary configration".
8. Energy saving operation mode.
9. Can use it for industrial usage.
