Trapezoidal vs Sinusoidal Brushless Servo Amplifiers May 23, 2013

Galil AMP-43540 Sinusoidal Servo Amplifier

Galil AMP-43540 Sinusoidal Servo Amplifier

The new Galil Sine drive amplifiers are a welcome addition to the existing DMC-40×0 and DMC-41×3 line-up of servo and stepper amplifiers – yet the addition of the new amplifiers also brings up a question  – “When should I use a sinusoidal drive instead of a trapezoidal drive?”.  This article will go over the Galil brushless servo drive architecture and highlight what you should know when making an amplifier selection.

Two Loop Architecture

In order to gain a better understanding of servo amplifiers and specifically how the Galil servo amplifiers work, the first thing to do is to understand the Controller/Amplifier architecture.  Unlike most single axis drives on the market, Galil uses a split sample rate.  The first and highest speed sample rate occurs on the amplifier and is used on the current loop.  The D3540 Sinusoidal amplifier runs its current loop at 33 kHz and the D3040 Trapezoidal amplifier runs at 66 kHz (which can be increased to 120 kHz for low inductance applications).  The benefits of a high speed current loop are:

  • Fast response to desired current/velocity command signal
  • Less destabilizing phase shift on the position loop
  • Tighter more accurate control – 16bit resolution
  • High Closed Loop Frequency (3-4 kHz)

The second loop in the system is the position loop.  Because of the limitations of real world mechanics, a position loop generally has a closed loop frequency in the range of 20 to 200 Hz.  The sample rate required to achieve this is only from 1 kHz to 4 kHz.  Note that the DMC-4000 can have a sample rate of up to 16 kHz and can control up to 8 axes allowing all axes to be tightly coupled.  General motion control applications run optimally at a 1 kHz position loop update.  High performance and high resolution applications can be run at higher rates depending on the required performance.

Separate processors for the Amplifier and Controller allow for this two loop Architecture which allows Galil to be extremely responsive and highly accurate and also perform whatever functions are required in a user’s application.

Trapezoidal vs. Sinusoidal Commutation

Trapezoidal commutation is the most cost effective way of controlling a brushless servo motor.  It is perfect for higher speed applications and applications where the motor and mechanics will eliminate the torque ripple that occurs during switching current from one phase to the next.  Hall sensors are required for Trapezoidal commutation.

Sinusoidal commutation is great for lower speed, direct drive or linear motor applications where the torque ripple of the motor phases needs to be minimized.  Since the current to the motor phases are weighted as sine waves, the torque going through the motor is smooth and has minimal ripple.  It also allows the mechanics to be simplified because Hall sensors can be eliminated.

Sinusoidal amplifiers rely on an initialization sequence at power-up to provide the correct commutation.  This can be done in one of 3 ways on the Galil.    The first and most common method is the BX command that uses an algorithm that energizes the phases and determines the brushless angle.  Only a small amount of motion (if any) is shown with this method.  The second method is to use the BC command that requires Hall sensors to be hooked up.  It will move the motor and use the first hall transition as the basis for the commutation.  This method is necessary if there is an external force on the motor such as a gravity load.  The third method uses the BZ command to drive the motor to the zero degree commutation point which can result in a jump to the closest zero phase.

More info on Galil Sinusoidal Amplifiers

The new AMP-43540 drives four brushless motors operating at up to 8 Amps continuous, 15 Amps peak, 20-80 VDC.  The gain settings of the amplifier are user-programmable at 0.4, 0.8, and 1.6 Amp/Volt.  The amplifier offers protection for over-voltage, under-voltage, over-current, short-circuit and over temperature. A shunt regulator option is available.  For more information, please see: DMC-40×0 Product Page .

Sin/Cos Encoders and Sinusoidal Drives help Galil Controllers Achieve Ultra-Precise Motion May 18, 2013

Introduction

The use of linear motors for precision motion applications has increased as technology has improved.

Galil DMC-31012 Motion Controller

Galil DMC-31012 Motion Controller

A linear motor typically uses a servo drive with sinusoidal commutation to minimize torque ripple and provide quiet smooth motion. It is also becoming more common for linear motor manufacturers to provide position feedback in the form of an analog sin/cos encoder as this method uses the signals from the motor magnets and is more cost-effective.  Galil motion controllers now provide options for sinusoidal drives and interpolation of sin/cos analog feedback for smooth control of ultra-high performance applications.

Galil controllers use an intelligent interpolation algorithm allowing inexpensive sin/cos signals to be used successfully in high-precision applications.   The AF command is used to set the analog feedback resolution at 2n counts/period. Galil drives perform sinusoidal commutation and are easily programmed using a choice of three different commutation methods.  An example showing how to configure Galil controllers and sine drives for use with linear motors with sin/cos encoders is below.

An example of a Galil Controller used with a Copley ServoTube Linear Motor

Galil’s DMC-31012 motion controller with an internal 800W sinusoidal drive and sin/cos feedback interpolation option was used  in an application with a Copley ServoTube linear motor with  sin/cos encoder. The goal was to move a stage and maintain a position accuracy of .04mm.   The stage manufacturer specified a 25.6 mm/sin feedback period for the encoder signals which is equivalent to the motor’s magnetic cycle.

The AF command was used to interpolate the analog feedback at 2n counts/period. N= 10 was used for this application.  AF 10 provided an interpolation of 1024 counts/period.  The system position resolution can be calculated using the equation below:

Resolution = 25.6mm /1024 counts = .025mm/count

.025mm/count resolution is within our target accuracy of .04mm.

It’s important to note that sin/cos feedback sensors are analog and more prone to noise compared to a digital signal. The DMC-31012 allows an AF of 12 but AF 10 was chosen because it met the accuracy specifications while minimizing the affect of noise.

There are three methods to initialize sinusoidal commutation with Galil sinusoidal drives, BI, BZ and BX.  For this application, the BZ command method was selected because it was better for high static friction. The BI command, which uses halls to initially commutate, is ideal in most cases but the Copley motor did not provide Hall sensors.

Another parameter used for commutation was the BM command.  BM is the brushless modulus of the system or the length for which one magnetic cycle completes. For the Copley ServoTube, the motor’s sin/cos period is the same length as the motors magnetic cycle.  For AF 10, the setting for BM is 1024.

Once AF, BZ and BM were configured during initialization, the controller system was tuned for optimum performance using the GalilSuite tuning software.

Galil controllers with the sin/cos feedback option and sinusoidal drives provide a good solution for controlling linear motors with a high degree of accuracy and extremely smooth commutation. Sinusoidal drives and sin/cos feedback options are available on Galil’s DMC40x0 multi-axis controller and the DMC-31012 single-axis controller.

For more detailed information, see application note #5523 “Connecting to a Linear Motor with Sinusoidal Commutation and Sin/Cos Feedback.” http://www.galilmc.com/support/appnotes/miscellaneous/note5523.pdf

Galil Tech Talk: Master Slave Networking with multiple controllers December 7, 2012

Posted by Servo2Go.com in Technical Support Information.
Tags: , , , , , , , , , , , , , ,
add a comment

For users that need to expand their IO across multiple devices, Galil Ethernet based controllers have a built-in Master/Slave capability.   This means that if a system has an Ethernet based DMC motion controller yet needs to add one or more RIO units to expand the IO capability, the DMC controller can be set up to reference the RIO inputs and outputs automatically.   Likewise, if a system needs to have multiple RIO Pocket PLC units – any one of those units can be set up as the “Master” controller such that it automatically references the i/o of all of the slave units.   The only limits to this are  the number of Ethernet handles that the master RIO or DMC unit has available. (Note: use the TH command to see how many handles a particular product has available).

Galil DMC-30000 with RIO PLC

Galil DMC-30000 with RIO PLC

Here are the steps to get a Master/Slave system working with 4 RIO units (1 master and 3 slaves):

Step 1)  Connect to each RIO unit with Galil software and assign an IP address.  A helpful nomenclature is to use the last 2 digits of the controller serial number as the last field of the IP address so its easy to remember what each units IP address is.

Step 2)  Use the following code-generator and input the IP address of each of the slave units:

http://www.galilmc.com/support/downloads/dmc_code/master-with-multiple-slaves.php

click “Generate Code”.  Then copy/paste the dmc program code that is generated into the Galil software Editor when connected to the “Master” controller.  Download and Execute this code (XQ).

Step 3) In the response window, you should see the following text:

SLAVE(s) CONNECTED
Set flag=x where x is 1-6

by looking at the code, you can see that the “flag” variable controls different types of i/o requests to the slave units.   As a simple test, set flag=1 in the terminal and this will cause output 1 on each of the slave devices to start blinking every 1 second.  Use the other included routines as a starting point for controlling the slave analog and digital  i/o for your system.

More details on setting up a Modbus slave device can be found in this article:
