Frequently Asked Questions

What type of cabinet is required for this IP00 drive?

• You must install this MR-J3-15KA4-LR in a fully enclosed industrial control panel. The panel should have a minimum IP54 rating to protect the drive from dust, debris, and accidental contact, as the drive itself has no enclosure.

Can this drive run a 10kW motor effectively?

• Yes, a 15kW drive like this one is well-suited for a 10kW motor. It provides headroom for peak torque demands and is a common practice to ensure reliable performance and longevity of both the motor and the amplifier.

How do I handle the regenerative energy from a large motor?

• This drive has five built-in 10-ohm resistors to dissipate moderate regenerative energy. For high-inertia or frequent braking applications, you must connect the recommended external dynamic brake unit to prevent fault overloads.

Is forced cooling noisy?

• The cooling fan will generate audible noise, typical for drives of this power. For noise-sensitive areas, consider installing the cabinet in a separate room or using acoustic paneling, while ensuring the drive's ventilation needs are still fully met.

What cables are needed to connect this drive?

• You will need main power cables (3-phase and ground), motor power cables (U, V, W), a brake cable, an encoder feedback cable, and the RS-422 communication cable. Always use shielded cables of the specified gauge to minimize electrical noise.
