Energy saving function
It has excellent automatic energy saving function, only need to set
the maximum energy saving target, as long as
the operation meets the energy saving condition, it can enter the
automatic skill state.
By setting the VF function, it can realize the application of 1
drag and long distance control to meet the application of
the transformation occasion.
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:
Applications
