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:

• SME20 – 6SL3055-0AA00-5EA3
• SME25 – 6SL3055-0AA00-5HA3
• SME120 – 6SL3055-0AA00-5JA3
• SME125 – 6SL3055-0AA00-5KA3

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

The Siemens SINAMICS G120 inverter has been designed for the accurate and efficient control of the speed and torque for three-phase motors. The Siemens SINAMICS G120 system comprises two basic modules, the Control Unit (CU) and the Power Module (PM).

PM230 Power Modules, are focused on the HVAC industry sector especially for pump and fan applications. The Power Modules are available with class-A filter or unfiltered in a rated power range from 0.37 kW to 90 kW and a line voltage range from 3 AC 380 V to 480 V. The PM240 Power Module comes with resistor braking and dc braking functions, and a supply voltage of 3 AC 400 V. The PM250 Power Module includes the regenerative braking function, and a supply voltage 3 AC 400 V. For the power modules, induction motors are permissible in the range from 25% to 150% of the inverter power without any restrictions. Wiring diagrams, specification datasheets, and user manuals are available on the MRO Electric and Supply website.

Some of the part numbers for these Power Supply Modules include:

• PM230 – 6SL3223-0DE33-7BA0
• PM240 – 6SL3224-0BE25-5AA0
• PM250 – 6SL3225-0BE25-5AA1

Maintenance is needed to preserve the specified condition of the Power Module. Dirt
and contamination must be removed regularly and parts subject to wear replaced. The
Power Module comprises mostly electronic components. Apart from the fan(s), the unit,
therefore, contains hardly any components that are subject to wear or that require
maintenance or servicing.

Siemens SINAMICS SMC10, SMC20, and SMC30 drives include high-performance single drives and coordinated drives (multiple-axis applications) with vector or servo functionalities that allow for implementation of truly customized high performance drive solutions for the ultimate in flexibility and increased productivity. In addition to an innovative system architecture and digital communication options, these drives come in a variety of designs and cooling types, each delivering performance from 0.16 to 6,000 HP, and feature efficient engineering and quick commissioning resulting from innovative tools and simple wiring. The SINAMICS series is built to be as streamlined with your automation operations as possible. Different Siemens SINAMICS S120 versions can be combined as required through the DRIVE-CLiQ interface.

A few of the popular modules for the SINAMICS S120 series of drives are the SMC Sensor Modules. The cabinet-mounted sensor module is necessary to evaluate the encoder signals of motors without  a DRIVE-CLiQ interface.

Part Numbers:

• SMC10 – 6SL3055-0AA00-5AA3 – Used for determining the actual motor speed and the rotor position angle
• SMC20 – 6SL3055-0AA00-5BA3 – Used for determining the actual motor speed and the path length
• SMC30 – 6SL3055-0AA00-5CA2 – Used for determining the actual motor speed

The SMC10/20/30 Sensor Modules feature the following connections and interfaces:

• 1 encoding connection including motor temperature sensing via SUB D-connector

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).

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:
