Application Scenarios
In a Taiyuan-based precision gear manufacturing plant, the 403M-P is used to control the indexing table servo of a gear hobbing machine. The drive’s high-resolution encoder feedback and electronic gearing function enable precise angular positioning of the workpiece, ensuring accurate tooth cutting. Its robust design withstands the oil and metal dust environment, while the fast current loop provides the high torque stiffness needed to resist cutting forces without losing steps.

Technical Principles and Innovative Values
- Innovation Point 1: Integrated Mains Supply & Compact Design. Unlike drives requiring an external DC bus power module, the 403M-P incorporates a switching power supply directly from 3-phase AC mains. This all-in-one design reduces cabinet space and simplifies power distribution, making it ideal for retrofitting into existing industrial panels in Taiyuan’s machinery plants where real estate is limited.
- Innovation Point 2: Advanced Anti-Vibration & Tuning Algorithms. The drive features sophisticated digital signal processing (DSP) with adaptive vibration suppression and model-following control. This allows it to automatically compensate for mechanical resonances common in long transmission systems (e.g., conveyor belts, printing presses), reducing settling time and improving surface finish in machining applications.
- Innovation Point 3: Flexible Fieldbus & Legacy Compatibility. The ServoStar 400 platform uses a modular communication card system. The base drive (403M-P) offers analog and pulse/direction interfaces, while optional plug-in cards enable seamless integration into modern EtherCAT, PROFINET, or legacy PROFIBUS networks. This flexibility allows machine builders to standardize on a single drive hardware platform across different generations of control systems.
