The power facility capacity varies depending on the power supply’s impedance.
The regenerative brake frequency shows the permissible frequency for decelerating the motor without a load from rated speed to a stop. When a load is connected, 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 frequen-
cy 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 regeneration heat generated (W) while operating and do not exceed the permissible value.
2-1. When a motor decelerates to a stop from the rated speed, the regenerative frequency will not be limited if the effective torque is within the rated torque range. When a motor deceler-
ates to a stop from the maximum speed, the regenerative frequency will not be limited if the load inertia moment is 8-fold or less and the effective torque is within the rated torque
range.
2-2. When a motor decelerates to a stop from the rated speed, the regenerative frequency will not be limited if the effective torque is within the rated torque range. When a motor deceler-
ates to a stop from the maximum speed, the regenerative frequency will not be limited if the load inertia moment is 4-fold or less and the effective torque is within the rated torque
range.
Contact Mitsubishi if the load/motor of inertia moment ratio exceeds the value in the table.
The shaft-through portion is excluded.
The vibration direction is shown in the right-side diagram. The numeric value indicates the maximum value of the component (commonly the bracket in the opposite
direction of the motor shaft). Fretting of the bearing occurs easily when a motor stops, so please maintain vibration to approximately one-half of the allowable value.
