Product Description

SF850 Series ac motor controller - motor speed controller

Main Introduction:
SF850 series drive is a universal magnetic flux vector drive, using a new modular design concept, mainly used to control and adjust the speed and torque of the three-phase asynchronous/synchronous motors, can be used for textile, paper, wire drawing, machine tools, packaging, food, fan, water pumps and a variety of automatic production equipment.

Product Characteristics:
SF850 series drive adopts the European-type modular design scheme. Unique structural design.
Make everything easy in the process of use!

1.Easy to install
* Key hole design
* Guide rail installation
* Spring-snap control terminal, no screwdriver required.

2.Convenient application
* Change the control module arbitrarily
* Can expand multifunctional I/O module, PG card and bus module at will
* Add software application macros for easy debugging
* Parameter copy function.

3.Simple after-sales repair
(1) It can be replaced damaged unit, such as OP panel, CM control module,
PM power module, PG expansion module, fan;
(2) When the PM is damaged, there is no need to replace the CM, which is
convenient to replace without adjusting the parameters and control lines,
greatly saving the after-sales cost and labor cost.
