If used in location such as actual site of machinery where oil or water may contact the product, special specifications apply, contact Mitsubishi.
The power facility capacity varies depending on the power supply’s impedance.
The regenerative brake frequency shows the permissible frequency for decelerating a stand-alone motor from rated speed to a stop. When under load, however, the value becomes the
table value divided by (m+1) where m is the load inertia moment divided by the motor inertia moment. When the rated speed is exceeded, the regenerative brake frequency is inversely
proportional to the square of (Operating speed/rated speed). When the operating speed varies with the frequency or when regeneration is constant (as with vertical feeds), find the re-
generation heat generated (W) while operating and do not exceed the permissible value.
The regenerative braking frequency of the 600W and smaller servo amplifier may fluctuate due to the affect of the power voltage since the energy charged by the electrolytic capacitor
in the servo amplifier is large.
There are no limits on regeneration frequency as long as the effective torque is within the rated torque range. However, the load/motor of inertia moment ratio must be 15 times or less.
Contact Mitsubishi if the load/motor of inertia moment ratio exceeds the figure in the table.
The shaft-through portion and connector for cable terminal are excluded.
The vibration direction is shown in the right-side diagram. The numeric value indicates the maximum value of the component (commonly the bracket on the anti-
load side). Fretting of the bearing occurs easily when the motor stops, so please maintain vibration to approximately one-half the allowable value.
MR-J2S-MCP (1)-S084 is also compatible. The compatible motor is the same as the MR-J2S-MCP (1).
The amplifier software version compatible with the HC-KFS series 750W is as follows.

Notes:
1. Solid lines show torque characteristics for
3-phase 200VAC operation.
2. Torque characteristics are same for single-
phase 230VAC operation.
3. For single-phase 100VAC operation, torque
characteristics that are different from
above-mentioned 1 and 2, are shown in
broken lines.
4. The effective load rate will increase by
approx. 10% during a cold start, but will
drop after approx. ten minutes of operation.
5. Use the HC-KFS410 at 90% or less of the
effective load rate.
