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.
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-RFS series 3.5kW/5.0kW is as follows.
A type:Version B0 or above B type:Version B0 or above.
