EmailAC810 Series Standard AC drive for Multi-motors Overview
AC810 series are high-performance, high-end AC drive manufactured by Veichi Electric on years of technical accumulation and in-depth market research & demand analysis. Features like favorable control performance and flexible networking and expansion, modular design and common DC bus solution, safety and stability etc., all together guarantee solid drive core of energy saving and emission reduction, and meet the diversified needs on frequency conversion functions for industrial enterprises.
Product Features
Flexible Networking and Extensions
Net multiple protocols
- Modbus-RTU protocol: maximum baud rate 115200, 128 nodes, maximum distance 1000m.
- (optional for different models): 12M rate, 32 nodes, maximum distance 100m.
- Profinet protocol.
- CANopen protocol: 1M rate, 64 nodes, maximum distance 40m.
Extension functions supported
Encoder extension: TTL, HTL, UVW, Sin/Cos, Resolver.
Bus extension: CANopen, Modbus-RTU, Profibus-DP, PROFINET.
- Extend functions according to actual needs.
- Extension cards of encoders supported.
- Bus extension implemented on different models.
Modularized design & common DC bus solution
Modularized design
- Filter, rectifier, AC drive, braking and buffer all designed into independent and standard modules configured flexibly according to motor power.
- Book-like appearance design saving 30% space thus easier for cabinet layout.
- Standard design for volume production & delivery.
Common DC bus solution
- Energy from power generation and electricity between the AC drive modules can be exchanged through the common DC bus and saved 5%-30% off when feedback.
- Load lowering or crimping/unwinding.
- Rectifier module and brake module current are effectively reduced and so as system capacity.
- Unified power supply by rectifier unit reduces the main circuit switch and brake unit consumption.
- Difficulty and consumption of electric control system wiring is lowered to save cost.
