Selecting The Proper Cables For Your Servo System

Engineers devote a lot of time and effort designing highly efficient, reliable, and economical stepper or servomotor positioning systems. They select a motor, a controller, appropriate feedback circuits, and an amplifier to satisfy the specific motion system’s needs. Unfortunately, however, the signal and power cables connecting the components are often neglected until the project is nearing its end or worse yet, handed off to an electrician who lacks the proper training. Overlooking critical cable selection factors can deliver a system with lower than expected accuracy, frequent failures, low immunity from electromagnetic interference, and adverse affects on neighboring equipment.

This article will attempt to make sense of what is a complex and at times, confusing picture on How To Select The Proper Cables For Your Servo System.

How to Choose a Motion Bus

A new motion control project has landed on your desk, you know that it makes sense to connect automation components together using a network, but with so many competing networks to choose from how can you make the right choice?

This article will attempt to make sense of what is a complex and at times, confusing picture.

ERD electric rod-style actuators now available with increased force, load guidance, and NEMA or metric motor mounts

Tolomatic's ERD Series Actuators

Hamel, MN – Tolomatic has expanded its new line of ERD electric rod-style actuators to make the line more flexible than ever before. Enhancements such as ball screws, motor mounts for NEMA and metric stepper and servo motors, plus a guide option, make it possible to employ ERD actuators in many more types of motion control applications. Originally designed as an affordable replacement for pneumatic cylinders, the ERD has become a very economical actuator solution for applications such as product changeovers, pick-and-place, sorting and diverting, heat-staking and more.

“With the expansion of the ERD product line, engineers now can specify an affordable electric rod-style actuator with a wide variety of options to solve their application challenges,” says Aaron Dietrich, electric products manager, Tolomatic. “The addition of ball screw choices, a guide option and metric servo motor mounts makes the ERD a very flexible product family for the general automation industry.

”The addition of ball screw choices improves the force range of the ERD up to 200 lb. The combination of NEMA and metric motor mounts allows users to select their preferred brand of servo or stepper motor. All three sizes of the ERD are available with an optional external guide system that prevents rod deflection and rotation during operation. The guide also features a tooling plate for mounting hardware.The entire ERD product family can be delivered built-to-order in five days.

Using Linear Shaft Motors in Parallel

Many customers have heard from that with a “Linear Shaft Motor … you have the ability to drive two motors in parallel using only one encoder and one amplifier” while all other systems… “requires two drives, two controllers, and two encoders, connected together.”

Some of our customers have found this hard to understand how we can do this.  This article explains how the Linear Shaft Motor overcomes these issues.

Mercury II 5000 Encoders enable Motion Control Systems

MicroE's Mercury II 5000 Linear Encoder

MicroE Systems’ new Mercury II 5000 is a miniature, high-resolution optical encoder that gives motion system designers superior performance, accuracy, versatility, ease of use and low cost of ownership compared to other encoders in its class.

Mercury II is the latest innovation from MicroE Systesms. It is the next generation of high-performance miniature encoders and it outperforms every encoder in its class. Importantly, it is also the easiest encoder to use. The sensor works with our PurePrecision™ laser tape metal scales, as well as glass linear and glass rotary scales. Mercury II also offers stick-on index and limit markers, robustness against contamination and EMI/RFI interference.

Galil Introduces Servo Drives with Sinusoidal Commutation

Galil is pleased to introduce two multi-axis servo drives that perform sinusoidal commutation: the AMP-43540 which contains four 600Watt servo drives and the AMP-43640 which contains four 20Watt servo drives.  Both models are sinusoidally commutated which minimizes torque ripple compared to drives using trapezoidal commutation.   This is especially important for applications using low friction linear motors.

Galil's New Servo Drive with Sinusoidal Commutation

The new AMP-43540 and AMP-43640 4-axis drives are available as options for Galil’s DMC-40×0 Accelera and DMC-41×3 Econo motion controllers with Ethernet. Designed to minimize space, cost and wiring, the drives reside directly inside the controller enclosure.   Two 4-axis drive units can be specified inside 8-axis controller models.

The new AMP-43540 contains four 600W fully digital, transconductance amplifiers for driving brushless motors with sinusoidal commutation.  Each amplifier drives 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. Both the switching and sampling frequencies are 33 KHz.  The amplifier offers protection for over-voltage, under-voltage, over-current, short-circuit and over temperature.  A shunt regulator option is available.  The U.S. list price of the AMP-43540 4-axis 600W drive is $1000 US in single quantity and $600 US/ea in 100 quantities.

The new AMP-43640 contains four 20W linear, transconductance amplifiers for driving brushless motors with sinusoidal commutation. Each amplifier drives motors operating at up to 1 Amp peak, 15-30 VDC with a gain setting of 0.1 Amp/Volt.  The U.S. list price of the AMP-43640 4-axis 20W drive is $600 US in single quantity and $350 US/ea in 100 quantities.

When using the AMP-43540 and AMP-43640 sinusoidal drives, hall sensors are not required for brushless motor commutation. Galil provides commands for initialization of the motor using the encoder feedback.
