1 Introduction:
For a long time, the small servo drive systems used in the machinery industry are mostly Japanese products, with low prices, stable performance, and simple application. This is the basic reason for customers to use Japanese products in large quantities. However, under some complex application conditions with high precision and high dynamics, Japanese servo products cannot meet customers' application requirements due to their single functions and poor integration.
2.Sinamics S110 / S120 AC / AC single axis servo drive system
Sinamics S110 / 120 AC / AC single-axis servo drive system is two high-performance single-axis servo drive systems that Siemens Company will soon launch following the S120 DC / AC multi-axis servo drive system. Both have integrated position loops, powerful I / O interfaces and communication ports, and share the same PM340 power unit. The difference is that the S110 only supports one servo (Servo) mode, while the S120 supports V / F mode. Mode and servo mode.
3. Application of S110 / S120 AC / AC single-axis servo drive in cable arrangement
a) Developed single-axis horizontal and vertical CNC cable routing systems
b) Developed a dual-axis cross CNC cable system
c) Realize any specification of take-up reel with constant tension and constant line speed, including I-disc, double cone disc, etc.
d) Realize non-stop automatic switching between take-up reels of any specification
4. Application advantages of Sinamics S110 / S120 AC / AC single-axis servo drive system in cable arrangement
a) The high reliability of Siemens motion control products, 1FK7 high-performance motor, to ensure that the equipment is vibrated in high temperature dust, etc.
In the harsh production environment, it can work stably for a long time under the condition of high-speed and high-frequency reciprocating motion.
b) The system comes with a large closed-loop position control function, high positioning accuracy, fast response, positioning function is completed by the device independently
This reduces the burden on the control system, simplifies the mechanical design, and eliminates the position encoder at the low speed end.
c) Integrated PROFIBUS-DP, and PROFINET, CAN and other field bus interfaces, making the servo device very easy
The ground is integrated into the control system based on S7-300, which reduces the signal wiring and realizes full digital control
Control, greatly reducing the impact of interference zero drift.
d) The application of Drive-Cliq interface ensures error-free installation of the servo system, simple debugging, suitable for OEM mass installation
Assembly production, while digital feedback greatly improves the reliability of the system
e) Modular design, easy installation and maintenance, low maintenance cost, minimize the loss caused by the fault to the user. f) The quality of the cable has been greatly improved, the shape of the disk is well-balanced, the full-disk rate and the genuine product rate are greatly improved, and it is easy to unwind the subsequent process
It is the above advantages that enable S110 / S120 to stand out from many Japanese and European and American products, accepted by users and used in batches, occupying 100% of the domestic market, and exported to South Asia, Europe and the United States.
