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.

Independent duct design
Independent air duct design, effectively preventing dust entering
inverter, causing short-circuit and other faults and improving
reliability;
Use bigger air volume and long life cooling fan effectively reduces
the internal temperature rise of the inverter and ensures reliable
and stable operation of inverter.
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:
