Frequently Asked Questions
What does the conformal coating protect against?
It guards the circuit board inside against condensation, oil mist, dust, and corrosive atmospheres. This extends the life of the MR-J3-40BS-EB in non-sealed cabinets.
Can I use a three-phase power supply with it?
No, this model is specifically designed for single-phase 200-230V AC input only. Check your facility's power before ordering.
What is the 2-minute capacitor discharge for?
For safety. After turning off power, wait at least 2 minutes before touching terminals to avoid electric shock from stored energy.
Which motor series work best with this drive?
It is optimized for the Mitsubishi HF-MP (medium inertia) and HF-KP (low inertia) servo motor series in the 400W power range.
How do I connect it to a controller?
This base drive unit typically requires an optional communication interface card (like SSCNET or CC-Link) to connect to a network. The drive itself provides the power stage.
