3 Steps for Configuring Yaskawa VFD's over PROIFBUS

3 Steps for Configuring Yaskawa VFD's over PROIFBUS

Recently, I worked on a project that used a Siemens S7-300 PLC to control several Yaskawa VFD's over PROFIBUS. Although Yaskawa provides documentation to accomplish this, reading through manuals can be time-consuming. For someone only seeking basic speed control of the drives, I've prepared a step-by-step process on how to quickly setup and control any Yaskawa VFD over PROFIBUS using the Basic Data message package. Step 1: Setup Your Hardware Configuration Download the Y...

How to Set Up an MRP-based Ring Network in TIA Portal

One of the great, and underused, features in TIA Portal is the Network Topology tab of "Devices and Networks." It can enable you to accomplish a number of advanced tasks while simultaneously providing more in-depth network diagnostics. Today, I want to quickly show you how you can use Network Topology to configure a MRP-based Ring Network in TIA Portal. Why Ring Topology? There are many reasons why one might consider using a ring topology for your network. The most common one is ...

Relative Gearing to an External Encoder with a Siemens 1500 PLC

Relative Gearing to an External Encoder with a Siemens 1500 PLC

DMC has often encountered a scenario where a customer wants to have a motor drive follow the position of an external encoder. However, a regular 1500 PLC does not allow you to directly gear to an external encoder; this functionality requires a 1500T PLC. The T-series processors allow much more complex motion control, but are also more overhead for simpler projects. As it turns out, with a little creativity, it is possible to gear to an external encoder using a regular 1500 PLC. While you can&...

Conditional Triggered Device Trace in SiMotion Scout V4.4

This tutorial is for SiMotion Scout V4.4 HF6 with TIA Portal. Features may change in different versions. The Device Trace in SiMotion has built-in functionality that makes it easy to track down a pesky condition that might only happen once or twice per day. Rather than sit at the machine waiting all day for the fault to happen, you can set up a triggered recording and let Simotion do the work while you go get a cup of coffee. The following steps will walk you through setting up the trace conf...

Schneider MDrive Motor Integration with Siemens Programming

I have found little information for commissioning a Schneider Electric Lexium MDrive Stepper Motor and integrating it into a Siemens solution, so I decided to write about how I did it. Commissioning the MDrive Stepper Motor with the Schneider TCP Configuration Utility The software required for commissioning the drive is available for download on the Schneider Motion website. The software that I needed was the Lexium LMDxE TCP Configuration Utility Version 1.2.0.6 that includes the PROFINET...

Motion Control Solutions with Technology Objects in Siemens TIA Portal

This article goes through setting up and using the Siemens S120 drive inside TIA Portal after it has been configured in STARTER. While several other Siemens drives can be started with Siemens Startdrive (G120, G120C, G120D, and G120P), performing a hardware configuration of an S120 drive is not yet integrated into TIA Portal. I have heard that the next big release will have this feature! TIA Portal Setup In this example project I’m using an S7-1500 CPU and a CU320 control unit as seen ...

Automating Siemens S7 and SiMotion Tasks Using C# .NET

Siemens offers useful tools for accessing both Simatic and SiMotion projects programmatically, in the form of registered COM Type Library DLLs. These tools offer many exciting possibilities (well, it does if you're like me, and get excited by things like automating automation tools). If you have Simatic Manager installed, the following DLLs are registered with it: S7hcom_x 1.0 Type Library - The default location on my laptop is C:\Program Files (x86)\Siemens\Step7\S7BIN\S7HCOM_X.DLL) S...

PID with a Siemens S7-1200 PLC

PID with a Siemens S7-1200 PLC

A few weeks ago I had the chance to experiment with serial communications using a Siemens S7-1200 PLC outfitted with a CM1241 (RS-485 module). Due to the limited number of projects we've had using the 1200 line of PLCs, this was an office first. And while it was very straightforward, it was still a learning experience. Recently I had another chance to be DMC's S7-1200 pioneer - this time using the S7-1200's PID blocks, and luckily, not involving death by dysentery, cholera, or sna...

High-speed Position Latching using Yaskawa's MotionWorks IEC

High-speed Position Latching using Yaskawa's MotionWorks IEC

I was recently working on a multi-axis Yaskawa-based motion control project and ran into an issue using an in-software position latch. In this case, we were running a servo at fairly high speed and trying to record the encoder position when a sensor was triggered. It turned out that the PLC scan rate, servo speed, and gearing ratios involved were resulting in unacceptable accuracy issues. For this project, all programming was done using Yaskawa’s MotionWorks IEC Express. We were using a...

Successful Implementation of Siemens' SiMotion Shaftless Drive Standard

Successful Implementation of Siemens' SiMotion Shaftless Drive Standard

In many industries, shaftless drive technology has replaced the old mechanical drive systems. Instead of using mechanical gearing to force one axis on a machine to follow another one, servos are used. The servo technology reduces many of the flaws of a large mechanical gearing system as well as provides a lot of flexibility. This technology is in heavy use in industries such as the automotive, packaging, and printing. Using the shaftless drive technology requires the use of a motion controlle...

Converting legacy Acroloop Motion to an ACR 9000 controller

Converting legacy Acroloop Motion to an ACR 9000 controller

DMC started as a motion integrator (the M stands for motion). Even though we do a great many other things these days, we still maintain a strong competency in this area. We were recently contacted by a client who has an old Acroloop 2000 ISA based motion controller running on a Windows NT with 32MB of RAM. Their concern was that parts to repair this legacy motion equipment would be difficult to obtain and could result in undesired downtime. We set out to find the best way to update this appli...

Using FBVEL Gain for PID Servo motion tuning Acroloop

Using FBVEL Gain for PID Servo motion tuning Acroloop

I have been using Acroloop 9000 controllers to control a number of machines where one axis is a high-speed rotary motor that drives a mechanical cam-driven process. During operation of the machine, the motor accelerates from a stop to a constant high speed, and then back to a stop. The mechanical cam performs dozens of cycles during the process while the motor is at a constant speed. The difficulty in tuning this process is that the motor experiences changing loads and inertias as the mechani...

Solar Panel Project Featured in Design World

A Solar Panel Assembly Project that DMC recently completed was the basis for a feature article in Design World Magazine. The article can be found here. DMC provided controls engineering and programming services for a company that makes machines that are used in photovoltaic production facilities. The system developed utilized a Siemens 317T Controller which provided both discrete control as well multi-axis coordinated servo motion control. The customer benefits of the solution DMC devel...
