A servo amplifier (MR-J2S-MKM4-PX) without enclosed regenerative resistor is available for the servo amplifiers MR-J2S-11KA4/B4 to 22KA4/B4.
The optional regeneration unit will heat up to approx. 100°C (212°F), so do not directly mount it on a wall susceptible to heat. Use nonflammable wires or provide flame resistant
treatment (use silicon tubes, etc.), and wire so that the wires do not contact the optional regeneration unit.
Always use twisted wires for the optional regeneration unit, and keep the length as short as possible (5m (16.4 ft) or less).
Always use twisted wires for the temperature detector, and make sure that the detector does not malfunction due to inducted noise.
When installing cooling fans (approx. 1.0m
3
/min, M92 x 2 units) to increase the regeneration braking frequency, change parameter No. 0 (for MR-J2S-A type) or No. 2 (for MR-J2S-B type).
