Elevator Variable Frequency Drive Features

Smooth & reliable elevator control with variable frequency

Flexibility

  • Control of IM and PM motors in a single product, geared or gearless systems
  • Open loop or Closed loop vector (with incremental encoder) control of standard IM motors
  • Open loop or Closed loop (with incremental/EnDat encoder) control of PM motors

Comfortable Ride

  • Includes 5 independent S-Ramps allowing fine tuning of ride performance and jerk free travel
  • Short floor operation reduces carriage travel time
  • High motor switching frequency (max 32kHz) for quiet motor operation
  • Dedicated motor brake control algorithm for safe and smooth operation of the motor brake

Advanced Features

  • Anti-Rollback (With Encoder).
  • Rescue mode operation possible with external UPS
  • On-board simple PLC function allows custom application programs to be written and interfacing with a wide variety of control systems
  • Modbus RTU and CANopen as standard
  • Full load operation up to 50ºC with no de-rating
  • Safe Torque Off function (TUV Approved) built in as standard
  • Output contactor control for SIL 3 compliance

Easy to Use

  • Dedicated elevator drive with logical parameter and function groups
  • Factory parameter settings suited to simple elevator applications for fast start up
  • Drive setup using familiar elevator units
  • Standstill motor autotune – no shaft rotation – no rope removal required
  • Wireless parameterisation (Using Optistick with OptiTools Studio)

Enclosure Options
