● Introduction
Features
No homing required after power-on
Absolute encoders can identify the current position immediately after power-on, eliminating the need for a homing operation.
A single revolution can be divided into 540,672 pulses, providing positioning accuracy of up to ±30 arcsec, with some models achieving ±15 arcsec. Repeatability can reach ±5 arcsec.
Mounting grooves and threaded holes are provided on the rotating and stationary sections to facilitate installation and alignment. The hollow shaft also allows centralized cable routing.
Direct drive motors can drive relatively large loads while maintaining high rotational speeds, providing a compact solution with high torque density.
A variety of cam profiles can be selected according to application requirements, including Modified Sine (MS), Modified Trapezoidal (MT), Modified Constant Velocity (MCMC1), and Trapezoidal-Sine (TR) profiles, providing flexibility for different motion applications.
The rotating section of the drive mechanism is sealed on applicable models, helping prevent dust ingress. Some models are designed to meet the IP65 protection rating.
Energy is consumed primarily during rotation. When the rotary axis is stopped, power consumption is significantly reduced.
No additional lubrication oil is required, helping eliminate contamination caused by oil leakage.
The direct drive design eliminates the need for components such as a homing sensor, gearbox, and conventional motor, simplifying the overall mechanical structure and saving installation space.
Programs and operating parameters can be modified through a programming terminal, computer, or other control interface to accommodate different motion requirements, allowing one system to support multiple applications.
Support for open communication protocols such as CC-Link and DeviceNet can significantly reduce wiring requirements and associated costs.
The driver, motor, and cables can be configured with interchangeable components, allowing flexible combinations and making maintenance and system management more convenient.
