Part 5: Motion control + MQTT, OPC-UA, and other protocols for cloud services
In Part 4 of this series, we detailed edge computing and gateways for industrial machinery. Now consider the various protocols and communications leveraged in IIoT connectivity — for example, the SCADA, MES, and ERP architectures we already covered in Part 1 and 2 of this series. These are the most involved in IT/OT (operational technology) […]

With the new ctrlX AUTOMATION platform, Bosch Rexroth has eradicated the traditional boundaries between machine control systems, IT, and the Internet of Things. Centralized and decentralized automation topologies can now be created flexibly with the scalable platform. Thanks to a Linux real-time operating system, open standards, app programming technology, web-based engineering and a comprehensive IoT […]
Trinamic now offers ultra-silent stepper motor driver with step/direction interface
Trinamic Motion Control now sells TMC2226 stepper motor drivers for two-phase bipolar stepper motors providing up to 2.8 A (peak) and supply voltages ranging from 4.75 to 29 V. Programmable using single-wire UART and featuring some of Trinamic’s latest-generation technologies, the TMC2226 driver is suitable for design upgrades with compatible drivers. The TMC2226 uses StealthChop2 […]
What’s the difference between torque mode and velocity mode in servo control?
Servo systems are used when the application calls for precise control of position, velocity, or torque — or a combination of the three. Depending on the parameter being controlled, the servo system can be operated in torque mode, velocity mode, or position mode. Each mode requires control loops that allow the servo drive and controller […]
What is direct torque control (DTC) for AC induction motors?
Variable frequency drives control AC induction motors through one of several control schemes. Scalar control (also referred to as V/Hz or V/f control) varies both the voltage and frequency of power supplied to the motor to maintain a fixed ratio between the two. This keeps the strength of the magnetic field at a constant level […]
New VFD series features PM motor control, reduced energy usage
Mitsubishi Electric Automation, Inc. has released the newest addition to its lineup of variable frequency drives (VFD), the FR-E800 Series. The micro-drive features a built-in PLC, and will include safety functionality meeting IEC 61508 standards and support various networks, including Ethernet/IP, MODBUS/TCP, and the soon-to-be-released CC-Link IE TSN. The FR-E800 Series is designed for engineering, […]
Trinamic introduces small, lightweight servo controller module
TRINAMIC Motion Control introduces the TMCM-1617, single-axis servo controller module, designed for servo drives with 18A RMS and 8 to 28V dc supply voltage. The TMCM-1617’s EtherCAT, CAN and RS485 interfaces, ultra-lightweight aluminum housing (conforms with DIN EN 60529), and a cutting-edge feature set make the TMCM-1617 an ideal choice for medical, aerospace, and robotics. […]
Improving performance without machine redesign
