Reacting quickly to enquiries with a practical product and service offering is a key success factor in the constantly growing market of power electronics. An essential part of this, right from the design-in phase, is knowing and understanding the customer’s requirements and application to the core.
As a leading supplier and pioneer of device connectivity, Weidmüller pursues this approach right down to the finest detail and, in the case of Siemens SINAMICS V90 servo drive system in Nanjing China, excelled thanks to its know-how and expertise.
Power electronics requirements completely fulfilled
Siemens has been based in China for more than 140 years and is renowned there for its products and

technology in the fields of electronics, automation and digitisation. With the SINAMICS V90 servo drive system, the Siemens team in Nanjing concentrated predominantly on performance optimisation and simple handling.
The new member in the SINAMICS series is designed for general servo applications such as packaging and automatic assembly machines. Its pluggable connectors are reliable, safe and easy to wire. Furthermore, it has an integrated safe torque off (STO) as well as a wide voltage range from approximately 380 to 480 volts.
With the support of the Weidmüller power plug-in connector, Siemens in Nanjing achieves a particularly compact SINAMICS V90 design
“In terms of our products, we place great importance on all of the components used meeting our requirements without any compromise – right down to the connections,” explains Zhihui Dong from Siemens in Nanjing. “Weidmüller knows these requirements and provides exactly the right product for us with its power plug-in connector.”
6 connections and increased touch safety
The BLZ 7.62IT/06/180MF5 power plug-in connector for IT networks is equipped with six connections as standard, which is ideal for the Siemens servo drive system. Thanks to the increased touch safety of 5.5 mm, the connector may be used without any restrictions in 400-V IT networks in line with IEC 61800-5-1, and without any additional cover.
“It was not difficult to choose the appropriate connection system for the SINAMICS V90. Weidmüller’s BLZ 7.62IT has a self-locking middle flange, with which we could implement the predefined widths of only 60 mm in some places and thus achieve a space-saving design,” recalls Mrs. Dong.
“We were also impressed by the flexibility and service. In addition to custom-fit products and fast reaction times, Weidmüller offers constant support in the form of a partnership directly on-site,” adds Mrs. Dong.
