INVERTEK DRIVES Optidrive Elevator Series

The Elevator Variable Frequency Drive is the 2^nd 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.

Features:
1. Elevator Encoder - Optional feedback

• Incremental Encoders
• EnDat Rotary Encoders (EnDat 2.1 & 2.2) with simulated encoder output
• SinCos Rotary Encoder with simulated Encoder output

• Control of Geared and Gearless elevator systems in a single product
• Open loop or Closed loop vector (with incremental encoder) control of standard IM motors
• Open loop or Closed loop (with SinCos/EnDat encoder) control of PM motors

• 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 quite motor operation
• Dedicated motor brake control algorithm for safe and smooth operation of the motor brake

• Anti-Rollback (Open and closed loop operation)
• Rescue mode operation (Sine wave or square wave UPS), with easiest direction measurement for UPS longevity.
• On-board simple PLC function allows custom application programs to be written and interfacing with a wide variety of control systems built in as standard
• Modbus RTU and CANopen as standard
• Full load operation up to 50ºC with no de-rating
• Safe Torque Off function built in as standard
• Brake release monitoring (In compliance with EN81-20 protection against unintended car movement)
