Frequently Asked Questions
What is the function of this Siemens plug-in control unit?
The Siemens plug-in control unit is designed for use with the SIMODRIVE 611 drive system. It serves as a key component for controlling and monitoring the operation of servo motors and drives within the system.
Can this control unit be used for positioning tasks?
Yes, the Siemens 6SN1118-1NK00-0AA1 is specifically designed for positioning tasks, providing precise control for applications requiring accurate positioning.
What type of feedback systems can be used with this control unit?
This control unit is compatible with resolvers, which are used as feedback systems to provide position and speed information to the drive for accurate control.
Is this control unit suitable for high dynamic applications?
While the control unit can be used in dynamic applications, the maximum speed dynamic response may be limited due to necessary smoothing measures. It is important to consider the specific requirements of your application.
How does pole pair number affect the control unit's performance?
The pole pair number affects the speed actual value resolution and the dynamic response of the control unit. A higher pole pair number results in a higher encoder resolution and accuracy, but also in more zero marks around the circumference, which can affect the unique range for linear axes and the referencing process for rotary axes.
What are the typical values for the speed control loop with this unit?
Typical values for the closed speed control loop when using this unit include a -3dB limit frequency of approximately 160Hz to 240Hz and a rise time of around 4.3ms to 2.8ms, depending on the pole pair number.
Can I use a speed actual value filter with this control unit?
Yes, the control unit allows for the parameterization of a speed actual value filter to minimize noise and improve performance. The filter settings can be adjusted based on the pole pair number.
What should be considered when using resolvers with this control unit?
When using resolvers with the control unit, it is important to reference the motors to their zero mark as you would with incremental encoders. Additionally, the type of resolver (2-pole or multi-pole) will affect the encoder resolution, accuracy, and the referencing process.
How does the control unit handle noise generated by low speed actual value resolution?
The control unit can minimize motor noise caused by low speed actual value resolution through the use of a speed actual value filter and by potentially increasing the sampling time of the speed control loop.
What adjustments can be made to optimize the speed controller settings?
To optimize the speed controller settings, parameters such as the speed controller gain and integral action time can be adjusted to suit the specific application and improve the control unit's performance.
