Siemens A5E31006890

We purchased the brand new Siemens 6ED1055-A5E31006890 from Quanzhou Xin Yuan Technology for the renovation of the mining conveyor belt. The connection terminals have a large spacing, making the on-site connection much easier; compared to the previous model, it responds extremely quickly to torque, does not lose speed during heavy-load starting, has good heat dissipation and can withstand high loads, and the power consumption has significantly decreased.

Performance Secret

The most crucial feature of this Siemens 6ED1055-A5E31006890 is its load-carrying capacity. Previously, when using a generic driver to handle large inertia loads, there was always a total overcurrent alarm at startup. After replacing it with this one, the torque response time significantly shortened, and it could stably output torque at low speeds. There was no need to constantly check the parameter table to adjust compensation values.

Overall layout

When the cover of the Siemens 6ED1055-A5E31006890 is opened to inspect the interior, the power module is arranged in a compact and reasonable manner. The heat sink is closely attached to the IGBT, and the air duct design has no dead corners. Compared to the messy wiring, its wiring has been specially fixed. Not only does it look neat, but more importantly, the wire bundle will not tear the skin under vibration conditions, and it is also convenient for disassembly and assembly during maintenance.

Service life

We conducted continuous tests on-site for over half a year, observing the wear conditions of the capacitors and fans. The results were much better than expected. The film capacitors of this machine have excellent temperature resistance, unlike the old electrolytic capacitors which are prone to bulging. As long as the air duct is cleaned in time, this machine won't have any problem surviving for several more years in harsh environments.

Core Strengths

The core strength of Siemens 6ED1055-A5E31006890 lies in its algorithmic robustness. Especially in scenarios with significant voltage fluctuations in the power grid, other devices tend to shut down, but this equipment can overcome such situations through the regulation of the DC bus. This ability to adapt to various conditions without being picky about the circumstances has helped us save a lot of costs on installing stabilizers.

Social identification

Whether it's an experienced electrician or a newcomer, everyone gives it a thumbs-up when talking about it. Everyone thinks this thing is very reliable and has a very low failure rate. Unlike those inferior frequency converters that often break down. As long as it is used in the equipment, both the client and the owner feel at ease, and the acceptance process goes smoothly. This accumulated trust over many years is precisely the reason why it is the most highly recognized.
