Description
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.
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
2. Flexibility
- 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
3. 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 quite motor operation
- Dedicated motor brake control algorithm for safe and smooth operation of the motor brake
4. Advanced Features
- 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)
5. Easy to Use
Easy-learn parameter structure and programming 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
