Optidrive Elevator
Dedicated Elevator Drive

The Elevator Variable Frequency Drive is the 2nd generation 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 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.

Elevator Variable Frequency Drive also incorporates Safe Torque Off* as standard, and a range of features including Rescue Mode.

  • 5 independent S-ramps for smooth carriage control
  • Control of IM and PM motors
  • Rescue mode operation
  • Built-in EMC filter
  • Advanced on-board features
  • Easy to use
