Siemens Sinamics PM230, PM240, and PM250: Beyond the User Manual

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:

240

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 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:

Siemens Sinamics TM120 Terminal Module: Beyond the User Manual

Terminal Modules are used to add further input and output interfaces to the S120 drive system. Terminal Modules are connected to the Control Unit using DRIVE-CLiQ.  DRIVE-CLiQ is a proprietary networking system by Siemens that aims to prevent packet loss and removes some of the collision handling capability. This allows for a high speed deterministic system, but also means that the protocol is not suitable for wireless or slip-ring communication. The TM120 module is used in evaluating temperatures. The temperature is monitored for the following sensors:

  • PT100
  • PT1000
  • KTY84
  • Bimetallic NC contact

The TM150 features 2 DRIVE-CLiQ interfaces, 4 temperature sensor inputs, and one power supply.

tm120

The part number for the Siemens SINAMICS TM120 terminal module is 6SL3055-0AA00-3KA0.

The SINAMICS TM120 is just one of many additional components that are available for S120 systems. These control units significantly reduce system costs, as they increase functionality for positioning, safety integration, and drive control allowing all these functions to be controlled by one unit versus several. There is also additional flexibility with a high number of programming options and digital inputs. With up to 12 binary inputs, the modules’ high I/O count add ease of use. The additional Ethernet port expands programming options as well.

Determining if your FANUC Motor has a Keyway

There are a couple ways to figure out if your FANUC motor has a keyway:

The first is if you can visibly look at the end of the shaft and see the holes on the end of the coupling. If your shaft has one hole at the end in the very center, it is a slick shaft. If the shaft has three holes in a line, that means you have a keyed shaft.

Another way to check if you have a keyed shaft without being able to look at the shaft is reading the OEM label on the FANUC motor. Your motor may have one of two types of labels on it, the first being a yellow FANUC sticker and the other being a silver G.E. FANUC sticker. All of the silver G.E. FANUC stickers on motors have a # suffix indicating a keyed shaft, except for the tag #7000 which indicates that it is actually a slick shaft. The pictures below show what each tag looks like with the # tag.

ge-fanuc

fanuc

The yellow FANUC sticker is a little bit easier to determine. If the part number has the # tag at the end of it, it is a keyed shaft. If there is no # at the end of the part number, that means it is a slick shaft. Below is a picture of a yellow FANUC tag without the # tag.

Testing your Alpha Power Supply Module

The following is a set of instructions to help you get your Alpha Power Supply Module to read “- -” on the display and have a consistent 300 volt DC output:

  1. Turn off the power. Make sure the charge light is off before doing anything. Check for a short between the bottom and top buss bars. If there is a short, disconnect all modules until the short disappears. Once there is no short, continue.
  2. Feed a 3 phase input into L1, L2, and L3 of the the power supply. Between 200V and 220V AC for leg to leg connections and between 100V and 110V AC for let to ground connections.
  3. Feed 200V into the CX1A connector.
  4. Install a jumper onto the top/bottom pins of the grouping of 3 pins on the CX3/MCC cable coming into the power supply.
  5. Install a jumper onto the top two pins of the grouping of 3 pins on the CX4 cable on the power supply.
  6. Make sure that all screws on the PCB are tightly screwed in.

alpha-power-supply

After following this process, your power supply module should now read “- -” and have baseline voltage output. Sometimes you may not have the necessary equipment to make a diagnosis on your motor, but we do. MRO Electric and Supply offers high quality repair services on all motors and spindle drives so you don’t have to worry about it. Please take a look at our website to see all available brands and parts we can service for you. Our rebuilds for these size drives usually only take 2-3 days, which includes rebuilding the part, painting the part, and fully testing the part to ensure top quality.
