Limax

Absolute shaft positioning system reading a magnetic tape with an ELGO sensor to manage speeds and deceleration.

Absolute positioningCANopenELGO

7: Max nominal current

Overview

The Limax system manages the pulses from a car sensor reading a magnetic tape in the shaft, so that after shaft acquisition it determines the target speeds and the deceleration points where the board starts low speed.

ELGO Limax sensor connected in CANopen to the BR400 on port CAN4 (with the supplied CANbus terminator)
Drives up to 7 binary multi-step inverter speeds, each with its own deceleration distance (params N5 D2–D7)
On its own it needs a low-speed approach; paired with suitable inverters it enables direct-to-floor arrival
With safety devices it allows door pre-opening at the floor
