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 in-
versely 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 regeneration 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 capaci-
tor in the servo amplifier is large.
Contact Mitsubishi if the load/motor of inertia moment ratio exceeds the figure in the table.
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.
Install a cooling fan (approx. 1.0m

/min, M92).
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-LFS series is as follows. A type:Version B3 or above B type:Version B3 or above CP type:Version A2 or above
