Preface
Goodrive300-LIFT (GD300L for short) series inverters for lifts are the new generation of lift-dedicated
inverters, which use the GD control platform for development based on CHV180 series inverters.
Applying advanced variable frequency vector control and modular interface design, the product
improves the security reliability, control performance, and ease of commissioning and features the
following:
Compatible with asynchronous and synchronous motors.
Starting torque compensation control with weighing sensors: implements slide prevention by
setting parameters.
Starting torque compensation control without weighing sensors: implements precise control on
gearless synchronous-tractor lifts, which achieves stable startup.
Static identification on initial pole angles of synchronous motors: For permanent magnet
synchronous motors, autotuning can be executed when the motors are static. This simplifies the
commissioning process and is applicable to commission the motors in mechanical connection.
S-curve function: Acceleration (ACC) and deceleration (DEC) S curve algorithms improve the
comfortability during motor ACC, DEC, and stop.
Brake and contactor control function: controls contactors and braking based on lift running logic,
enhancing lift security.
ASR optimization: ASR uses variable proportional and integral gain control, providing dynamic
response in startup and stop states and improving comfortability during constant-speed running.
Forced DEC handling: prevents top-hitting and bottom-clashing during the upward or downward
running of lifts.
Emergency operation function: implements stop at convenient leveling for the equipment of
UPS and storage battery input interfaces.
Energy-saving operation: implemented for using the optional RBU series energy feedback unit.
