Abstract: GD300L 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 VVVF drive. Engineering practices, market survey and feedback show that GD300L has good control performance and stability compare to other brands.
Keywords: INVT GD300L, Johnson controller and Geared Machine, Elevator AC drive.

I.Introduction
GOODRIVE300L series inverters are the new-generation inverters developed based on INVT’s newest control platform. As using TI 28-series DSP and advanced vector control technology, Goodrive300L series inverter improved great achievements in security and reliability, control performance, use functions and basic performance.
Basic performance:
Ability to drive asynchronous (Geared) and synchronous (Gearless) motors
Support open loop control mode without encoder and closed loop control mode with encoder.
 Static motor auto tuning for the initial pole angle so that not required to de-roping of the motor
 Support multiple type of encoder: Support incremental, sine-cosine, absolute encoders.
 Energy saving running mode: Support the use of RBU, implementing energy saving running.
 Optional LCD keypad.

TUNNING PROCESS
STEP-1	P00.01=0
STEP-2	P00.09=2
STEP-3	MAKE SURE MOTOR CONTACTOR IDS "ON" AND DISPLAY IS SHOWING "TUN E"	IF MOTOR CONTACTOR IS NOT "ON" THEN PRESS IT EXTERNALLY WITH TESTER OR SCREEWDRIVER
STEP-4	THEN PRESS GREEN COLOUR (RUN) BUTTON OF DRIVE
STEP-5	DISPLAY WILL SHOW RUN-1…RUN-2…RUN-3…AND THEN "END" AND MOTOR TUNNING WILL SUCCEED. IT WILL TAKE 120 SEC.
STEP-6	MAKE P00.01=1 AND TRY TO RUN THE MOTOR WITH UP OR DOWN COMMAND.

III.Conclusion
After installation of the gd300l drive in three different type of elevator application as for
1. Gearless Motor (Close loop with encoder)
2. Geared Motor (Close loop with encoder)
3. Geared Motor (Open loop without encoder)
It is concluded that the gd300l drive gives very nice performance with easy debugging.
