Features

Safety & Reliability

1.Compliant with EU CE and RoHS environmental certifications.

2.Adopts a unique DC bus architecture to completely eliminate crosstalk between conventional standalone servo drives.

3.Built-in standard STO (Safe Torque Off) function, with multi-axis safety-linked emergency stop mechanism and IP25 protection degree.
Diverse Control Algorithms

1.Built-in gantry synchronization with a 62.5μs control cycle.

2.Supports pressure closed-loop, tension closed-loop, and full position closed-loop control.

3.Multi-axis coordination enables high-speed data sharing between modules at 400MHz.
High Efficiency & Energy Saving

1. Adopting a common DC bus architecture, it reduces average energy consumption by approximately 30%. Typical savings: 40%~60% for all-electric injection molding, and 30%~40% for printing applications.

2. Ultra-low braking loss greatly lowers the internal temperature of the electrical cabinet and reduces the failure rate of internal electrical components.
Easy Commissioning

1. Equipped with multiple commissioning tools, supporting three debugging methods: PC software, keypad, and master station network.

2. Single USB Type‑C port enables one‑click copying and downloading of multi‑axis parameters for batch configuration replication.

3. The streamlined and efficient PC software generates multi‑axis motion curves to quickly pinpoint process issues and optimize control cycles.
Cost Savings

1. Space Cost: Saves 30%~50% of electrical cabinet space and improves space utilization.

2. Maintenance Cost: The built-in black box function accurately locates intermittent faults, cuts troubleshooting time and downtime losses, and greatly reduces maintenance costs in unattended operation scenarios.

3. Operating Cost: Delivers an average energy saving rate of approximately 30%, helping end users reduce costs and boost efficiency.
Motor

1. Self-developed 25-bit optical absolute encoder with potting process, featuring low temperature rise and low electromagnetic noise.

2. IP65 high ingress protection rating.
