The power facility capacity varies depending on the power supply’s impedance.
The regenerative brake frequency shown is the permissible frequency for decelerating a stand-alone motor from rated rpm 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 rpm is exceeded, the regenerative brake frequency is inversely proportional to the square of (Operating speed/rated speed).
When the operating rpm varies with the freqency 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 vibration direction is shown in the right side dagram. The numeric value indicates the maximum value of the component (commonly the bracker on the antiload side).
Fretting of the bearing occurs easily when the motor stops, so please maintain vibration to approximately one-half the allowable value.
For servo motors with electromagnetic brake please refer to page 17.
