Looking Inside the Siemens Sinamics CU305, CU310-2, and CU320-2

Electronically coordinated single-motor drives work in unison to perform your all of your drive needs. In multi-axis drives, the individual drives are controlled from a higher-level control system in a way to achieve the desired coordinated movement. A centralized Siemens SINAMICS Control Unit has control over the drives for all connected axes and also establishes the links between the drives and/or axes. Since all required data is stored in the central Control Unit, it does not need to be transferred. The CU310-2 is used in conjunction with power modules and single-motor drives whereas the CU320-2 is used with all motor modules or line modules for both single and multi-motor drives.

Different versions of these control units include:

All of these control units are based on an object-oriented SINAMICS software called SIMOTION. The firmware included contains all common control modes and can be scaled to meet almost all automation requirements. This firmware will contain instructions for infeed controls for main infeeds, and all vector an servo controls.

Looking Inside the Siemens Sinamics SME20/25 and SME10/125 Encoder

The encoder system is connected to the SINAMICS S120 via DRIVE-CLiQ. Motors with DRIVE-CLiQ interfaces are designed for this purpose. These motors simplify commissioning and diagnostics because the motor and encoder type are identified automatically. The Sensor Modules(SME20, SME25, SME120, and SME125) are only to be used with machines and may ONLY be connected to the DRIVE-CLiQ interfaces of proprietary components. Direct encoder systems outside the cabinet can be connected to the Sensor Modules External. The SMEs evaluate these encoder systems and convert the calculated values to DRIVE-CLiQ. No motor or encoder data is stored in the Siemens SMEs. The Sensor Modules External provides the encoder power supply. The power supply for the SME is provided from the connected DRIVE-CLiQ cable. This should be taken into consideration when selecting the DRIVE-CLiQ cable. SMEs have a higher degree of protection(IP67) which means it is suitable to be installed on the outside of the cabinet.

Part numbers for the SMEs include:

Below is a chart that shows the connectable encoder systems between the SMC and SME modules.

Siemens Sinamics VSM10 Module: Beyond the User Manual

The Voltage Sensing Module VSM10 is integrated in chassis format AIMs but may also be used to improve booksize ALMs compensation for fluctuations in the supply voltage. An Active Interface Module (AIM) is essential for the operation of an ALM. The AIM contains a reactor and filter to ensure compliance with category C3 (EN 61800-3) EMC regulations. An additional EMC filter is available for booksize modules to restrict emissions to within limits set by category C2(EN 61800-3) EMC regulations – however, a TN supply is required. The VSM10 provides a feed forward control signal of the actual supply voltage rather than requiring the ALM to detect and then react to any fluctuations in the DC bus. It  is used to operate a permanent-magnet synchronous machine without encoder with the requirement for switching to a machine which is already running (flying restart function).

VSM10

The VSM10 features the following interfaces:

  • 1 connection for direct voltage sensing up to 690 V
  • 1 connection for voltage sensing using voltage transformers, maximum voltage 100 V
  • 1 temperature sensor input (KTY84‑130 or PTC)
  • 1 DRIVE-CLiQ socket
  • 1 connection for the electronics power supply via the 24 V DC supply connector
  • 1 plug-in jumper for either grounded (delivery state) or isolated measurement
  • 1 PE connection

The status of the VSM10 Voltage Sensing Module is indicated by a two-color LED. The VSM10 Voltage Sensing Module can be snapped onto a TH 35 mounting rail according to EN 60715 (IEC 60715). Below is a wiring diagram for the the VSM10:
