3. The servo amplifier (MR-J2S-MKM-PX) without enclosed regenerative resistor is available for the servo amplifiers MR-J2S-11KA/B to 22KA/B.
4. Always use twisted wires for a thermal sensor, and make sure that the sensor does not fail to work properly due to inducted noise.
5. When increasing the regeneration braking frequency, install cooling fans (approx. 1.0m
3
/min, M92✕2 units) and change the parameter No. 0 (for MR-J2S-A type) or No. 2 (for MR-J2S-B
type). The cooling fan must be ordered by user.
