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:
The KD600E driver is a special frequency converter for K-Drive elevators. They provide V/f control, including voltage and frequency separation control.
