Professional FAQ – Selection & Experience

Q1: Can this module drive a 10 A motor?

No. Rated L‑axis output is 6.5 A. For higher current, choose the H205 or H206 series.

Q2: What is the real‑world thermal performance?

We tested it at 50 °C ambient – output derates linearly above 45 °C. Keep forced airflow > 2 m/s.

Q3: How to select between H103 and H205?

H103 is for light‑duty axes (≤6.5 A). H205 offers 12.5 A for heavy‑load spindles. Check your motor nameplate.

Q4: Does it support regenerative braking?

Yes, internal regenerative circuit handles up to 10% duty cycle. Use external resistor for higher inertia loads.

Q5: What maintenance is recommended?

Inspect DC‑link capacitors every 3 years. Clean heatsink quarterly – dust reduces thermal headroom.
