The VDL200 drive series is designed for low and medium rise geared applications in both open and closed loop with asynchronous motors.

High-performance control algorithms allow installation in sensorless configuration while maintaining the comfort level provided by highrange inverters.

Simple installation and configuration make the VDL200 ideal for modernizing the present systems as well as for the new installations.

 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
• Lift sequence: Typical sequence of input/output signals used in lift engineering applications such as I/O management, braking, output contactor and door control.
• Parameters in linear unit: Possibility of selecting different engineering units for the main movement parameters, rpm or m/s for speed, m/s2, m/s3 for car acceleration.<>/li
• 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 car. Two independent S-shaped ramps, selectable via digital input with 4 independent jerk settings. Dedicated deceleration ramp corresponding to the stop command.
