Abstract: GD380L is special elevator drive developed for all type of elevator like home lifts, passenger and goods lifts etc. This paper gives the detailed solution installation and commissioning details for GD380L. Engineering practices, market survey and feedback shows that GD380L has good control performance and stability.

Keywords: INVT GD380L, Geared Machine.

I.Introduction
GOODRIVE380L series inverters are the new-generation elevator inverters developed on the new INVT control platform. Goodrive380L series inverter improved great achievements in security and reliability, control performance and use functions Basic performance.
Basic performance:

1.Ability to drive asynchronous (Geared )and synchronous (Gearless) motors
2.Support open loop control mode without encoder and closed loop control mode with encoder.
3.Static & rotational motor tuning for the initial pole angle of PM motor
4.Support multiple type of encoder: incremental, sine-cosine, absolute encoders and built in incremental PG card
5.ACC/DEC S-Curve Algorithm: Improve comfort during ACC, DEC and stop.
6.Starting weight compensation with and without weight sensor to prevent reverse slip at startup, ensuring stable lift startup.
7.Emergency-rescue mode & search the direction in light load.
Special functions
8.In-Built LCD keypad interface.
9.In-Built Incremental PG card.
