Xinshida Motion Control System in the Application of Parallel Robots in the Robotics Industry
Project Background
A parallel robot is defined as a closed-loop mechanism in which the moving platform and the fixed platform are connected via two or more independent kinematic chains, featuring two or more degrees of freedom and driven in a parallel configuration.
By mounting the motors on the fixed platform, parallel robots achieve a lightweight design for their moving parts, enabling them to offer advantages such as light weight, high speed, and rapid cycle times. Coupled with vision inspection systems and dynamic gripping capabilities, these robots are widely used in light industries—including food, pharmaceuticals, and electronics—where they excel in material handling, packaging, and sorting tasks, providing unparalleled benefits and significantly boosting production efficiency on assembly lines.
The common parallel robot shown in the figure below is a four-axis machine capable of translational motion along the three spatial axes—X, Y, and Z—as well as rotational motion about the Z-axis. Its mechanical structure features a motor connected directly to a reducer, which in turn is linked to the main arm. The main arm is connected to a secondary arm via limiters. A fourth axis, located either on a fixed platform or a moving platform, enables rotation about the Z-axis. During operation, the motor drives the main arm to swing up and down within a specified angular range, thereby precisely positioning the moving platform through the action of the secondary arm.

Scheme advantages
1. Wall-mounted servo
The robot control system is connected to the Ωm-N1 drive via an EtherCAT bus. Each drive is equipped with axes 1, 2, 3, and 4 of a Delta robot. The one-key rigidity adjustment function enables simple and rapid tuning of system responsiveness, significantly reducing customers’ debugging time. Thanks to the drive’s 3-times overload capacity and hardware current-loop response, the system can achieve a cycle rate of up to 200 cycles per minute even under standard gate-shaped test motions. An advanced tuning algorithm effectively minimizes vibrations generated by the mechanical structure during high-speed operation.
Thanks to its outstanding power density, the Singlina Ωm-N1 product can reduce its installation volume by approximately 30% compared to servo drives of similar power. By adopting a wall-through mounting method, it further optimizes the space inside the cabinet and enhances the enclosure’s protection rating.
2. Intelligent drive, one-click adjustment
As shown in the figure, with the one-click auto-tuning function built on the Ω platform, customers can easily perform auto-tuning. The tuned parameters directly meet the equipment’s operational requirements, significantly reducing the debugging time for field operators.
3. Runs smoothly without shaking.
Thanks to the outstanding trajectory-shaping algorithm of the Ω platform, under the same control commands, the shaping algorithm effectively reduces current fluctuations during equipment operation. Even during high-speed rhythmic operations exceeding 200 cycles, the system can still ensure smooth mechanical performance, thereby extending the service life of the mechanical components.
4. Multiple protections for peace-of-mind use
When parallel mechanical systems are operating at high speeds, the rapid cycle times can pose serious collision risks in the event of an accident if robust safety protection features are lacking. The Omega platform series of servo drives is equipped with advanced protection functions—including dynamic braking, vertical drop detection, command anomaly detection, and anti-fall protection—that can maximize the safety of both customer equipment and personnel in the event of an accident, thereby minimizing losses caused by unforeseen incidents.

Project Results
The Ω platform servo uses the standard 402 protocol and is compatible with mainstream control systems available on the market, including robot control systems from Keba and other manufacturers.
● Compact size to meet customers’ customized requirements.
The Singularity Ωm-N1 drive is perfectly suited for parallel robot configurations. Its compact size—small enough to fit comfortably in one hand—helps customers save valuable space in electrical cabinets. By opting for bracket mounting, installation space can be further minimized, fully meeting customers’ customized requirements.
● Dynamic braking to prevent runaway vehicle collisions.
With the help of the dynamic braking function, collisions caused by uncontrolled vehicle movements due to abnormal commands or actions are avoided.
● Worry-free trial operation, saving debugging time
The motor features self-identifying capabilities, eliminating the hassle of customer debugging. With just a single rigid parameter, it can meet customers’ diverse response requirements, significantly reducing tuning time.
