Material Composition
Internal high-performance digital signal processor (DSP) and industrial-grade power modules. External high-strength aluminum alloy housing providing excellent heat dissipation and electromagnetic shielding.
Structural Features
Compact modular design supporting DIN rail or panel mounting. Equipped with standard terminals and keyed connectors for straightforward wiring.
Working Principle
The drive converts input AC power through a rectifier to DC bus voltage, then uses a three-phase PWM inverter to output precise three-phase AC to drive the servo motor. The internal DSP continuously samples motor feedback signals and executes current, speed, and position three-loop closed-loop control algorithms.
Installation Requirements
- Must be installed inside a control cabinet with protection rating no less than IP20.
- Ensure adequate cooling space above and below the drive.
- Route power cables and signal cables separately to avoid electromagnetic interference.
- Must be reliably grounded through a low-impedance path.
Usage Notes
- Confirm power supply voltage matches the drive nameplate before powering on.
- Execute motor configuration and auto-tuning through setup software on first run.
- Regularly inspect cooling passages to prevent dust accumulation causing overheating.
- Wait for DC bus voltage to drop to a safe level before performing any maintenance after power disconnection.
