Siemens 6SL3055-0AA00-4BA0 Overview

The Siemens part 6SL30550AA004BA0 is an electronic component with technical specifications that make it suitable for various applications. This part is designed to be used with a resolver system, providing accurate feedback for motor control. These products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry HMIs from other manufacturers such as FANUC and Yaskawa.


The electronics power supply of the 6SL30550AA004BA0 operates at a voltage range of 24V DC (with a tolerance of 20.4V to 28.8V DC). The maximum current consumption of the part, without an encoder system, is less than or equal to 0.20A. However, with an encoder system, the current consumption increases to a maximum of 0.35A. The power loss of the part is specified to be less than or equal to 10W.


One of the key features of the 6SL30550AA004BA0 is its ability to work with resolver systems. The transformation ratio of the resolver (ü) is a crucial parameter, and for this part, it is set to 0.5. The excitation voltage on the SMC10 (an associated component) when the transformation ratio is 0.5 is 4.1V RMS. The amplitude monitoring threshold on the secondary tracks of the SMC10 is specified as 1V RMS.

The excitation voltage for the resolver, which cannot be parameterized, is set at 4.1V RMS. The excitation frequency is synchronized to the current controller clock cycle and operates within the range of 5 to 16 kHz.


The 6SL30550AA004BA0 is equipped with a PE/ground connection that is established at the housing using an M4 screw tightened to 1.8 Nm torque. The maximum length of the encoder cable that can be connected to this part is 130 meters. With a weight of 0.45 kg, this part is compact and lightweight.


Regarding protection, the 6SL30550AA004BA0 has an IP20 degree of protection or IPXXB, providing sufficient protection against solid objects and the ingress of fingers. It is important to ensure the appropriate level of protection is maintained during installation and operation.

Additionally, the maximum frequency that can be evaluated (speed) by the resolver system connected to the 6SL30550AA004BA0 depends on the number of poles and pole pairs. For a 2-pole motor, the maximum speed that can be evaluated is 120,000 rpm when the resolver operates at 8 kHz/125 μsec, 60,000 rpm at 4 kHz/250 μsec, and 30,000 rpm at 2 kHz/500 μsec. The maximum speed decreases as the number of poles and pole pairs increases.

In summary, the Siemens part 6SL30550AA004BA0 is an electronic component designed for use with resolver systems. With its specific voltage and current requirements, it offers reliable operation and accurate motor control. Its compact size, appropriate protection rating, and compatibility with different pole configurations make it a suitable choice for various industrial applications requiring resolver feedback for motor control.
