Gefran ADL300 (VFDs)

Gefran frequency inverter ADL300 desctription

The ADL300, designed for new installations and upgrades, is the ideal system for a wide range of applications, including very low rise (home lifts) or very high rise (skyscrapers). Its software, developed for geared (including open loop) and gearless (closed loop) lifts with absolute or incremental encoder, guarantees maximum safety and control.

Precise landing at the floor, with both direct landing and creeping, and load compensation at start give passengers an extremely comfortable ride. The ADL300’s compact size and operation in contactor or contactorless mode make it perfect for Machine Room-Less (MRL) applications.

ADL300A, optional cards on request:




"Safety" inputs
For use with a single output contactor or in contactorless mode

Back-up power supply
The ADL300 guarantees operation even in the event of a power failure. It features an automatic return-to-floor function managed by an external device such as UPS or buffer battery via a singlephase 230V AC power supply (with EMS module).

Lift control system
Basic and advanced lift functions are incorporated in a single product, to ensure maximum comfort for all systems at all times:
- Speed control: EFC (Elevator Floor Control) function: separate function for independent management of short floors, landing zone, re-starting with lift not at floor and automatic deceleration point calculation.
- Position control: EPC (Elevator Positioning Control) function: separate function for independent management of direct arrival at the floor with internal position regulator and saving of floor distances (system autotuning).
- Lift sequence: Typical sequence of input/output signals used in civil lift engineering applications such as I/O management, braking, output contactor and door control.
- Parameters in linear unit: Possibility of selecting different engineering units (also with values for the US) for the main movement parameters, rpm (fpm) or m/s for speed, m/s2, m/s3 for cabin acceleration.
- Lift mechanical parameters: Mechanical system parameters such as pulley diameter and speed ratio for converting system units and weights, system for calculating inertia and speed regulation for the desired response.
- Ramp generation: Independent configuration of acceleration and deceleration ramp parameters and of the 4 jerk values for maximum travelling comfort in the lift cabin. Two independent S-shaped ramps, selectable via digital input with 4 independent jerk settings. Dedicated deceleration ramp corresponding to the stop command.



Integrated keypad
The integrated programming keypad allows fast programming and immediate start-up.
- 1-line x 4-character alphanumerical LED display with sign
- Simple parameter modification
- Menu and individual parameters displayed in numerical format
- Fast navigation keys
- Alarms / messages and startup wizard displayed in text format

SD card port
The SD memory card makes saving and loading data and configurations with the ADL300 very simple. (Special adapter required KIT KEY SD-CARD, cod. S72644.)

Fieldbuses
The ADL300 integrates the most advanced fieldbus technology used in the lift sector:
- DCP3 for use in EFC (Elevator Floor Control) mode
- DCP4 for use in EPC (Elevator Positioning Control) mode
- CANopen and CANopen Lift (CiA®417) for lift control systems

Configuration technology
The ADL300 is fitted with RS232 serial communication with Modbus RTU protocol.

Optional programming keypad
The optional KB-ADL programming keypad featuring full display of parameters and variables in 5 languages makes the ADL300 extremely intuitive and easy to use. It has a strip of magnetic material on the back so that it can be attached to the front of the drive or other metal surface (e.g. door of the electrical panel).

The keypad can be used remotely from distances of up to 15 m. A 70 cm-long connection cable is supplied as standard. Up to 5 sets of parameters can be saved using the KB-ADL keypad and sent to other drives.
