  4. High protection: double independent air ducts, IP56 fan.

The future has come

A new generation of integrated servo products, combining control, power, and braking into one. Simplify installation lines, reduce bridges, wire slots, connectors, and line nodes, reduce equipment complexity, increase space utilization, and increase installation efficiency by more than 5 times.

Subversion begins

  1. Subvert the traditional installation method: There is no need to control the electric cabinet, and the original motor installation method is not changed. It saves space while improving production efficiency, reducing the probability of production errors and the cost of error correction.
  2. Less radiation and distributed capacitance: Internal wiring helps improve the EMC electromagnetic compatibility of the system, greatly reduces interference, and ensures the stable operation of the system.

Easy to use

  1. The essence of technology is to provide better services: It is not an upgrade process, but an iteration. What changes is not the product, but the thinking.
  2. Integrated brake function: The whole system has built-in brakes and brake resistors, eliminating the work of selecting and installing wiring, completely avoiding faults and damage caused by incorrect selection or improper selection of components.

Intelligent temperature control

70,000 hours of the long-life fan (IP65 protection), combined with multi-point temperature detection, intelligent control of fan operation, low load, and long standby conditions are particularly obvious.

New experience

  1. AC300V-AC450V wide power input: The ultra-wide AC input voltage range can calmly deal with various grid environments and improve the equipment's adaptability under extreme working conditions.
  2. IPM permanent magnet synchronous power design: IPM built-in magnetic steel design, low-temperature rise, fast response.
  3. Strong overload: The weak magnetic algorithm, more than 2 times the torque, can easily cope with overload and overspeed conditions.

Powerful kernel

  1. Multi-unit control: Multiple joint control modes such as synchronization, follow, superimpose, and intelligent tracking are available.
  2. Multiple signals are given: Analog quantity, communication, internal, terminal multi-speed.
  3. The movable keyboard can be extended, can be installed independently: The keyboard adopts an RJ45 network cable interface and supports hot-swap. It can be extended long distances and can be installed independently with a bracket.
