Key Features

• High‑precision HRV (High‑Response Vector) control for fast, accurate positioning.

• Rugged, compact yellow housing with aluminum fin heatsink for reliable cooling.

• 7‑segment LED display and diagnostic LEDs for real‑time status and fault indication.

• Comprehensive protection: overcurrent, overvoltage, undervoltage, overtemperature, fan fault, IPM fault.

• Regenerative braking returns energy to the power supply, improving efficiency.

Common Alarms

• AL‑01: Overvoltage (HV) – DC bus voltage too high.

• AL‑02: Low control voltage (LV) – control power supply fault.

• AL‑03: Low DC link voltage (LVDC) – insufficient DC bus voltage.

• AL‑05: Over‑regenerative discharge (DCOH) – regenerative energy excessive.

• AL‑08: L‑axis IPM alarm (IPML) – L‑axis power module failure.

• AL‑06: L‑axis overcurrent (HCL) – motor current overload.

Installation & Safety Notes

• Disconnect all power before installation or maintenance.

• Confirm the “CHARGING” LED is off before handling to avoid electric shock.

• Maintain ≥50mm clearance around the unit for airflow and cooling.

• Securely tighten mounting screws to resist vibration.

• Periodically inspect fan operation, terminal tightness, and heat sink cleanliness.

• If an alarm occurs, stop the machine immediately and check motor, wiring, and PSM.

Application Range

• Heavy‑duty CNC machining centers, high‑power lathes, grinders, and multi‑axis robots.

• Single‑axis high‑power applications requiring precise, stable motion control。
