Closed loop control has been a very popular option on the STAC5 drives and recently we’ve added to its functionality. Previously the dynamic “stall prevention” feature was only available via stored programs or streaming commands, but now by popular demand this feature is accessible in step and direction mode and encoder following mode. Check out Jeff Kordik’s Encoder Feedback in Step Motors Systems video to see and hear more about closed loop control of step motors.

Ease of use is always high on the lists. To that end, the STAC5 family is the beneficiary of our new fully integrated ST Configurator™ software. With the new ST Configurator, the Q Programmer™ is built in – which means no switching between programs and all the tools you need are in one place. The ST Configurator software makes setting up, configuring and programming STAC5 drives a snap. All motor, I/O, encoder and motion control parameters are available to the user through an intuitive interface. The ST Stepper Drives with Ethernet video provides a nice overview of the basics of getting an Ethernet drive started up.

Like many of our drives the STAC5 series has several modes of control. Users can choose between step and direction, streaming serial commands, Q programming, and EtherNet/IP communications. For EtherNet/IP users we continue to add programmer’s tools and application notes designed to make interfacing with PLC’s quick and easy. There are three application notes available for now: one for connecting to Allen Bradley MicroLogix PLC’s, one for connecting to Allen Bradley ControlLogix and CompactLogix PLC’s, and one for Add-On Instructions in Allen Bradley’s RSLogix5000. Keep an eye on the Application Notes section of the web site under the Support menu for more notes and programming examples to come.

The STAC5 series of drives delivers the highest step motor performance and ease of use available anywhere. With the new closed loop operation in step and direction mode, the all-in-one ST Configurator software, and application notes with example code, the STAC5 drives are even better. Check out the STAC5 series today.

STR2 Microstepping Drive from Applied Motion Products

STR2 Microstepping Drive from Applied Motion Products

The STR2 stepper drive is an ultra compact, digital step & direction drive, great for OEM applications requiring basic step & direction control of a 2-phase step motor. The STR2 outputs up to 2.2 A/phase to the step motor, and is compatible with a variety of 2-phase step motors that have been selected to optimize performance of both the drive and motor.

The STR2 drive features advanced microstepping performance and sophisticated current control with anti-resonance. Anti-resonance electronically damps motor and system resonances, which improves motor smoothness and torque over a wide speed range.

Each STR2 step motor drive operates in either Step & Direction or Pulse/Pulse control mode. Selecting between these two modes is done by moving a jumper located under the cover of the drive. Each STR2 drive can microstep up to 20,000 steps/rev with a 1.8º step motor (1/100 step), and can even microstep the step motor when the command pulses are low resolution. This feature is called Microstep Emulation. All drive setup is done via dip switches on the side of the drive, including motor selection, running current, idle current, and step resolution.

Galil DMC-30000 Pocket Motion Controller

Galil DMC-30000 Pocket Motion Controller

Greenville, DE —  Servo2Go.com announces the release of the new Galil DMC-30017 single-axis controller with microstepping drive and also the DMC-31xxx option which includes a 16-bit ADC and accepts sinusoidal encoders.  

DMC-30017 Pocket Motion Controller with 6A/phase microstepping drive
Galil’s DMC-30000 Pocket Motion Controller Series includes the DMC-30012 which combines a single-axis motion controller and 800W brushed/brushless sine drive in a single, compact package.  Now, Galil introduces the DMC-30017 controller/drive package for stepper motors.  The DMC-30017 contains a microstepping drive for operating a two-phase bipolar stepper motor.  The drive produces 256 microsteps per full step or 1024 steps per full cycle which results in 51,200 steps/rev for a standard 200-step motor.  The maximum step rate generated by the controller is 3,000,000 microsteps/second.  The DMC-30017 drives motors operating at up to 6 Amps at 20 to 80 VDC.  There are four software-selectable current settings: 0.75A, 1.5A, 3 A, and 6A.  A selectable low-current mode reduces the current by 75% when the motor is not in motion.  The DMC-30017 is compact, measuring  3.9″ x 5.0″ x 1.5″,  and no external heat sink is required.

The new DMC-30017 is $745US in single quantity and $480US/ea in 100 quantities.  It is available for shipment now.

DMC-31xxx Option for 16-bit ADC and Sinusoidal Encoder Input
The DMC-31xxx model increases the ADC resolution from 12-bits to 16-bits and provides +/-10V configurable analog inputs, and provides an option for accepting sinusoidal encoder signals instead of digital encoder signals.  The DMC-31xxx interpolates a 1-volt differential sinusoidal encoder resulting in a higher position resolution.  The AFn command selects sinusoidal interpolation where n specifies 2n interpolation counts per encoder cycle (n=5 to 12).  For example, if the encoder cycle is 40 microns, AF10 results in 210=1024 counts per cycle, or a resolution of 39 nanometers per count.

The DMC-31xxx model increases the price of the DMC-30xxx by $100US in single quantity and $65US/ea in 100 quantities.  For example, the DMC-31012 is $795 in single quantity.

The Many Uses of Encoder Feedback March 22, 2012

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

Step motors are popular in part because they are low cost and easy to use.  But experienced users know that if the system demands more torque than the motor has available, the motor stalls.  Compounding the situation is the fact that stepper systems don’t require feedback, so other devices in the system are unlikely to be aware of the stall.  However, by adding an inexpensive encoder, the drive can monitor the motor’s actual position directly, closing the feedback loop and avoiding many of the limitations traditionally associated with stepper systems.

AMP STAC5 with motor and encoder

By adding an encoder to the system to track rotor position, the drive can know precisely how far and how fast the motor has moved.  Thus, the first use of encoder feedback is position and velocity verification.  A PC or PLC can monitor position and velocity over RS-232, RS-485, CANopen, Ethernet or EtherNet/IP.

A step motor is constructed with a permanent magnet rotor that turns on bearings, and a stator, a series of electromagnets surrounding the rotor.  When the drive sends electric current through the stator, the resulting electromagnetic field forces the rotor to react.  If the stator current is properly controlled, a step motor can perform impressive feats, accelerating at precise rates to exact speeds, and stopping on a dime with great accuracy.

Because step motors produce less torque at high speeds, they can stall if overloaded.  The second use of encoder feedback is the immediate detection and reporting of stalls.  The driver can be configured to signal other equipment by the state change of a digital output or by providing this information over the communication interface. 

The encoder also allows for real time monitoring of the torque producing lead/lag angle, the angular difference between the magnetic fields of the stator and rotor.  Applied Motion drives can use this information to precisely control the motor’s torque and prevent unexpected motor stalls, the third and ultimate use of encoder feedback.  Stall prevention is enabled by checking the “Stall Prevention” box in our ST Configurator™ set up software.

Encoders can be purchased with Applied Motion motors ranging from NEMA size 11 to 34.  The encoder comes pre-assembled to the rear shaft of the step motor and connects  via cable to the encoder feedback port available on many of our drives, including our DC powered ST5  and ST10 and the AC powered STAC5 and STAC6.

Sensorless Homing in Integrated Stepper Motors March 16, 2012

add a comment

Integrated Stepper Motor's from Applied Motion ProductsDigital Signal Processing (DSP) provides the foundation for much of the latest stepper control innovation. Precision current control via custom algorithms within the DSP and encoder feedback allow today’s stepper drive technology to detect stalling of a step motor.  Applied Motion Products takes this technology a step further by providing the logic necessary to allow user control of the system current in a near-stall situation to ride through or prevent most stall conditions.

One additional benefit to the stall detection current control is the ability to apply user logic via Q Programmer. Moving to a hard stop, with stall detection enabled, provides the ability to detect a stall situation relative to position and reverse off of a hard stop to a predictable and repeatable home position.  User selectable idle and running currents provide a quiet and smooth homing routine eliminating noise and vibration at end stops improving motion control accuracy and reliability through intelligent fault recovery.  Adding an encoder to any Applied Motion Products stepper motor with today’s current control (provided by proprietary algorithms in the Applied Motion Products DSP) allows for stall detection, stall prevention, and sensorless homing in Integrated Stepper Motors.
