Lifts/Elevators control
We have vast experience delivering the right variable frequency drives into Lifts/Elevators control applications.
The key requirements for world class elevator control
Ride comfort
The elevator must move smoothly with strict limits set on acceleration to avoid any jerky movements
Start / Stop
Some elevator systems are rated for up to 240 start/stops per hour, requiring special attention to manging the amount of heat this will cause the motor to generate.
Levelling accuracy
An elevator is required to stop with precision, this could be as little as 1 or 2mm.
Speed feedback
Speed and position feedback is necessary to ensure speed control, levelling accuracy and ride comfort are delivered to the required standard.
Electrical braking
Electrical braking is required for accurate speed control of the lift with mechanical braking utilised as a parking brake.
Variable frequency drives dedicated to elevators
Optidrive Elevator is the dedicated elevator drive from Invertek Drives, designed to provide smooth, reliable carriage control in all elevator applications.
The compact external dimensions simplify installation, whilst optional incremental, EnDat & SinCos encoder feedback interfaces allow compatibility with a wide range of motors. Invertek’s renowned motor control capability ensures maximum ride comfort under all conditions, with five independent S-Ramps and dedicated motor holding brake control algorithm allowing fine tuning of the system.
Optidrive Elevator also Incorporates Safe Torque Off* as standard, and a range of key elevator features including Rescue Mode with light load detection and short floor operation.
