The new Trinamic-branded PD42-1-1243-IOLINK intelligent actuator by Maxim Integrated Products has enabled modern smart factories to quickly and remotely adjust an actuator’s electrical characteristics to minimise factory downtime and maximise throughput. It combines a NEMA-17 stepper motor with controller and driver electronics.

With Trinamic now part of Maxim Integrated, the PD42-1-1243-IOLINK uses the flexibility of Maxim Integrated’s MAX22513 IO-Link transceiver to allow seamless configuring of all modes of Trinamic’s TMC2130-LA motor driver. As a small, low-power NEMA-17 PANdrive solution, the intelligent actuator monitors 50% more configuration and performance parameters to reduce commissioning times as well as improve the quality of predictive maintenance data.

The new chipset solution of TMC2130-LA motor driver and MAX22513 IO-Link transceiver builds upon the benefits of IO-Link’s two-way universal interface. The PD42-1-1243-IOLINK intelligent actuator incorporates motion control technology into a plug-and-play solution that is 2.6x smaller and more than 50% lower power compared to the competitive solution. It brings intelligence to the factory floor by providing 50% more parameters compared to the competitive solution to help improve predicting factory shutdowns and maximise factory throughput.

The PD42-1-1243-IOLINK intelligent actuator includes the following chipset:

MAX22513: The MAX22513 IO-Link transceiver is a small ±1kV/500Ω surge-protected, dual-driver IO-Link transceiver (4.2x2.1mm WLP package). It features high integration with a DC/DC regulator, protection diodes, auxiliary digital input, I²C or SPI control, integrated oscillator and selectable 3.3V or 5V LDO which help to provide high configurability and reduce SKU. It enables four times lower power dissipation due to low 2.0Ω (typ) C/Q driver on-resistance compared to the competitive solution.

TMC2130-LA: The TMC2130-LA motor driver offers stall detection with no sensors necessary, unlike the competitive solution, to flag unwanted mechanical behaviour. It provides extremely smooth and precise motion with up to 256x microstepping compared to the 16x industry standard, resulting in accurate positioning and minimised resonance. Key integrated functions include a complete driver stage with low RDSon N-channel power MOSFETs configured as full H-bridges to drive the motor windings up to 1.2A RMS at 5-46V, an SPI interface for configuration and diagnostics, as well as a step-direction interface.

Advantages

  • Increased productivity: Adjusts more device parameters on-the-fly by providing access to load values and noise reduction parameters using StealthChop technology to dynamically optimise actuator throughput performance.
  • Lower power: CoolStep power savings feature of TMC2130-LA, combined with low RDSon N-Channel power MOSFETS of MAX22513 provides best-in-class power savings compared to other NEMA-17 IO-Link drives on the market.
  • Small size: PD42-1-1243-IOLINK provides the smallest IO-Link intelligent actuator by eliminating external limit switches to detect hard stop conditions resulting in a solution size of 82cm³.

The PD42-1-1243-IOLINK is available at Trinamic’s authorised distributors; pricing available at authorised distributors. The MAX22513AWJ+T is available at Maxim Integrated’s website for $3.94 (1000-up, FOB USA); also available from authorised distributors. The TMC2130-LA and TMC2130-TA are available at Trinamic’s authorised distributors; pricing available at authorised distributors.
