OEM Single Phase Elevator Inverter 7.5 MV VFD Vector Control
KD600E Series Elevator Lift Single-phase Transducer High Frequency Converter elevator inverter close loop 7.5 Mv VFD
Product Introduction
KD600E High/Medium voltage VFD, integrating the cutting-edge international power electronic technology and vector control technology, greatly suppresses the input harmonic current on the grid side through phase shifting rectifier transformer, achieves voltage superposition through cascade connection of multistage H bridge power units and obtains almost perfect high pressure sine wave output. It can directly drive the high voltage motor without any filter and its harmonic indicator meets the requirements for the power harmonics in IEC std 519-1992 (International Electrotechnical Commission) and GB/T 12668.4-2006 (National Standard).
Technical features
* Flexible terminal expansion without the need for PLC.
The flexible terminal configuration and expansion and the digital/analog input/output terminal functions may be flexibly expanded as required by the user without the need for PLC programming. Only corresponding parameter functions shall be set.
* Vector Control
Calculate the motor speed and achieve the AC motor decoupling control accordin to the motor speed detected by the encoder and combines with the software vector control algorithm. The control performance may be comparable with DC speed regulation system.
Support constant power operation and support operation above base frequency (fluxweakening function).
* High quality drive of motor
Multi-level PWM control mode and sinusoidal current output.
Common mode voltage and du/dt, no special requirement for motor and cable, frequency conversion renovation of old equipment without the need for motor replacement.

Single multi-speed terminal elevator controller
For the elevator controller with only one multi-segment speed changing terminal, the high-speed segment and the layer speed segment are controlled by the on-off of the high-speed terminal. The wiring diagram of such elevator controller and frequency converter is as follows:

Double multi-speed terminal elevator controller
When the elevator is in use, if the system's power supply suddenly fails, it may result in passengers being locked in the car.
KD600E series elevator inverter can support the emergency UPS power supply operation for emergency power outage operati-on, and the emergency signal can be received by the inverter terminal DI6. The wiring diagram is as follows:
Closed loop elevator control
KD600E series elevator inverter can support closed-loop control, and provides a variety of PG cards for use with different encoders. Please refer to Chapter 5 of KD600 series User manual for PG card information. The wiring diagram of elevat-or controller and frequency converter for closed-loop elevator control is shown in the following figure:
