142955-7

The Yaskawa part number 142955-7 belongs to the Sigma 7 series and is categorized as a single-axis servo drive. This unit operates efficiently within a voltage range of 200 to 240 VAC while delivering a peak output current of 20 A. It is suitable for driving motors that vary in capacity from 30 W to 15 kW, making it versatile for a range of applications.

The drive utilizes the EtherCAT control protocol for fast communication, but it also presents other options such as Analog and MECHATROLINK, broadening its connectivity. With a response speed reaching 3.1 kHz, this servo drive provides excellent dynamics and control performance. Tuning is made simple with an automatic method that eliminates the need for manual adjustments.

In terms of stability, it includes advanced vibration control mechanisms, specifically anti-resonance and a ripple filter, to enhance performance. The encoder input is a high-resolution 24-bit absolute type that ensures precise feedback. Additionally, functional safety is a priority, incorporating Safe Torque Off (STO) with SIL3 and PLe ratings.

For users requiring flexibility in axis support, this module includes an option for dual-axis capabilities. The servo application is enhanced through motion refinement features, including friction and ripple compensation, to maintain smooth operation.

Lastly, the design allows for a slim profile that can be side-mounted, making it a practical choice for space-constrained environments without compromising on performance.
