The DISTANCE BASED VF CONTROLLER is the state of the art, latest technology Micro process based VF Controller designed for AC Geared Elevators for speed up to 2.5m/s and best suited for medium and highrise buildings with peak traffic.

SMD designed, Microprocessor control, Distance based Main Control board - EBAB 3.4

-Distance based software which converts encoder signals to actual hoist way distance
-Distance based profile achieved and stored through learn run
-High Performance Close loop Digital VVVF Drive
-Optimum rate of deceleration and minimum slowdown distance
-Direct approach to floor level without any creep run
-25% savings in flight time (between floor to floor run)
-10% additional savings in power consumption due to reduction in flight time
-Group operation for 2 Cars. Group operation works on the in-built relative system response
-(RSR) feature through serial communication resulting in shorter waiting time and higher traffic handling.
-2 line LCD display diagnostic test tool on main control board for site programmability and field test mechanism

    -On line operation status and Floor position
   -Actual life position in mm
   -Parameter programming
   -Fault diagnosis resulting in minimum down time for an maintenance
