Description

Product introduction

Adopt 32-bit motor-specific digital signal processor DSP, programmable ultra-large-scale logic device CPLD and intelligent power module IPM

Innovative no-load sensor start compensation technology, so that the elevator has excellent starting stability without installing a weighing device

Use incremental ABZ encoder to realize synchronous motor control, and use no-load sensor startup compensation technology to achieve excellent startup stability

The hardware adopts a new type of module, the junction temperature can reach 175°C, the switching and opening losses are low, and the service life is extended

Dual 32-bit embedded microprocessors jointly complete the elevator operation function and motor drive control

The anti-interference ability design exceeds the level required by industrial design

With rich and advanced elevator operation functions, it can fully meet the various needs of customers

Passed CE, UL certification
