SINAMICS A10: Intelligent Servo Drive System with Integrated Safety and Efficient Debugging

Provide options for input cascading and common DC bus. The common DC bus allows up to 6 drivers to parallel the DC bus, effectively recovering braking energy and reducing the use of external braking resistors. Drivers need to be arranged in descending order of power during construction.

3. Braking resistor configuration

The driver is integrated with an internal braking resistor. When the regenerative energy generated by motor braking exceeds its capacity, an external braking resistor needs to be connected. The manual provides detailed formulas for calculating braking energy and a selection table for external resistors (including continuous power, peak power, and resistance value requirements), and emphasizes the importance of using intrinsically safe resistors with temperature monitoring function, which must be activated on the driver side (through digital input DI4).

Debugging and Diagnosis: Application of Network Server

The revolutionary feature of SINAMICS A10 lies in its integrated network server debugging interface.

1. Debugging process

Debugging can be performed by accessing the driver service interface (default IP: 169.254.11.22) through a browser (supporting Chrome, Firefox, Edge, Safari, etc.). The main steps include:

Basic settings: Set the driver name and adjust the motor rotation direction.

One click optimization (OBT): Automatically optimizes the control parameters of the driver speed loop and current loop, and users can choose "conservative", "standard", or "dynamic" optimization modes.

Parameter settings: Configure speed/torque limits, brake control parameters, digital input functions (such as probes, external brake resistor temperature monitoring), etc.

Security integration debugging: Through a wizard interface, gradually configure security functions, select control methods (PROFIsafe/F-DI), set delay time, differential time, etc., and set security passwords to prevent unauthorized modifications.

Data backup and recovery: It is easy to backup all parameters to local files or restore settings from files, making it convenient for batch debugging or device replacement.

2. Diagnosis and maintenance

The network server provides a comprehensive diagnostic view:

Message Center: Centralized display of fault and alarm information, supporting filtering and viewing of details.

Drive status: Real time monitoring of key parameters such as speed, torque, current, temperature, etc.

Communication status: Display IP address, PROFINET connection status, and process data exchange status.

Security diagnosis: The dedicated page displays information such as the activation status of security functions, mandatory potential fault check (Teststop) timer, security logs (CRC checksum and changes), etc., for easy tracking of security status and recording of acceptance testing documents.

Technical advantages and application areas

The SINAMICS A10 servo drive system excels in the following areas with its high integration, excellent safety, and minimalist debugging experience:

Robots and robotic arm systems

Packaging, plastic, and textile machinery

Printing machinery

Glass, ceramic, stone and wood processing machinery

The system deeply integrates security functions into the driver, reducing the number of external security components and wiring complexity, while lowering debugging thresholds and maintenance costs through standardized network interfaces. The pre installed OCC cable and optimized motor driver combination ensure high reliability and consistent performance for plug and play use.
