Product Profile

6SL3053-0AA00-3AA1 is a Voltage Sensing Module (VSM10) from Siemens' SINAMICS S120 drive system. It is designed to precisely detect and measure line or motor voltage, providing critical feedback to the drive control unit for advanced functions like Safe Brake Control (SBC) and optimized motor control in demanding applications.

This module is the upgraded version of the previous VSM10 (6SL3053-0AA00-3AA0), available since spring 2013. Its key enhancement is galvanic isolation of the power circuitry from the grounded electronics, which significantly improves the insulation resistance to >10 MΩ. This is achieved through a connector (X530) that allows the internal voltage sensing circuit to be disconnected from ground potential, a feature especially important in IT systems.

The VSM10 is housed in a compact, booksize metal casing for DIN rail mounting. It communicates with the Control Unit via DRIVE-CLiQ and features connections for direct voltage sensing up to 690 V, as well as via voltage transformers.

System Role

The VSM10 Voltage Sensing Module serves as a precision feedback device within the SINAMICS S120 drive system. Its primary role is to measure the actual voltage present at the motor or on the line side and provide this data to the Control Unit via the DRIVE-CLiQ interface. This measurement is essential for several advanced control and safety functions.

One of its most critical roles is enabling Safe Brake Control (SBC). To safely release a holding brake, the system must verify that sufficient voltage is present at the motor. The VSM10 provides the safety-certified voltage measurement required for this function, making it indispensable for hoisting, vertical axis, and robot applications.

Beyond safety, the VSM10 enhances control accuracy by compensating for voltage drops in long motor cables or through output filters. This leads to better torque control, speed regulation, and improved overall motor performance. It also supports advanced diagnostics by detecting discrepancies that can indicate deteriorating cable insulation or other issues.

Compatibility notes:
  • The 6SL3053-0AA00-3AA1 is the upgraded version of the VSM10, providing galvanic isolation for the voltage sensing circuit, which is a key improvement for IT systems.
  • In new converters shipped with this module, the jumper at connector X530 can be removed during commissioning to achieve an insulation resistance of > 10 MΩ.
  • When replacing the older VSM10 (3AA0) with this new module (3AA1) in an existing converter, the jumper at X530 must not be removed for safety reasons, as it is required to discharge interference suppression capacitors in IT systems.
  • The module is compatible with all SINAMICS S120 Control Units that support DRIVE-CLiQ communication.

FAQ – Frequently Asked Questions

Q1: What is the purpose of the VSM10 module?

It detects and measures the line or motor voltage in SINAMICS S120 drives, providing critical feedback for safety functions (SBC) and optimizing motor control, especially in long cable or filtered installations.

Q2: What is the difference between 6SL3053-0AA00-3AA0 and 6SL3053-0AA00-3AA1?

The 3AA1 version is the upgraded VSM10, available since spring 2013, which features galvanic isolation of the power circuitry. This allows for a much higher insulation resistance (>10 MΩ) in IT systems by removing a jumper on connector X530.

Q3: How does the VSM10 improve drive control?

By measuring the voltage at the motor, the VSM10 allows the drive to compensate for voltage drops in long cables or through filters, leading to more accurate torque and speed regulation.

Q4: Is the VSM10 required for Safe Brake Control (SBC)?

Yes, the VSM10 is a mandatory component for the SBC function. It provides the safety-certified voltage measurement needed to safely release a motor holding brake.

Q5: Can the VSM10 be used in IT systems?

Yes, the upgraded VSM10 (3AA1) is specifically designed for IT systems. By removing the jumper at connector X530, the internal voltage sensing circuit is galvanically isolated, achieving an insulation resistance of >10 MΩ.
