STEP elevator all-in-one inverter AS380 4T07P5/4T0011/4T0015/4T18P5 Flashable protocol

Features

A) It is an organic combination of elevator control and drive. The entire device has a compact structure, small size and less wiring, high reliability, easy operation, and more economical;
B) Dual 32-bit embedded microprocessors jointly complete the elevator operating functions and motor drive control;
C) Redundant safety design, dual safety protection of the control processor and drive processor to achieve the strongest safety guarantee for elevator operation;
D) The anti-interference capability design exceeds the highest level of industrial design requirements;
E) Full CAN bus communication makes the wiring of the entire system simple, with strong data transmission capability and high reliability;
F) Adopt advanced direct parking technology to make the elevator run more efficiently;
G) It has rich and advanced elevator operation functions, which can fully meet the various needs of customers;
H) It has advanced group control function, which not only supports the traditional group control method of up to eight stations, but also supports the novel destination layer allocation group control method;
l) Using advanced vector control technology, the motor has excellent speed regulation performance and achieves the best comfort;
J) It has good versatility and is suitable for both synchronous motors and asynchronous motors;
K) The newly created no-load sensor starting compensation technology enables the elevator to have excellent starting comfort without installing a weighing device;
L) Incremental ABZ encoder can be used to realize synchronous motor control, and no-load sensor starting compensation technology can also be used to achieve excellent starting comfort;
M) New PWM dead zone compensation technology, effectively reducing motor noise and motor losses;
N) Dynamic PWM carrier modulation technology, effectively reducing motor noise;
O) Synchronous motors do not require encoder phase angle self-tuning;
P) If the motor parameters are set accurately, the asynchronous motor does not need motor parameter self-learning. If the precise motor parameters cannot be known on site, a simple static motor self-learning method can be used to allow the system to automatically obtain the accurate parameters of the motor without the need for complicated work such as lifting the car;
Q) The hardware adopts the 6th generation new module, which can withstand junction temperature up to 175℃, has low switching and turn-on losses, and extends the service life.
