The repeated frequency means the frequency of operation that the motor
rotates and stops regardless of the rotation direction of the motor. The
permitted repetition frequency means the maximum repetition frequency per
minute.
The motor regenerative resistor selection by the repetitive frequency is limited
to the loading operated in the horizontal direction.
Refer to the below formula to calculate the maximum allowable repetition
frequency of the load system.

• Contents necessary in calculation shall be referred to the below.
• n is the inertia ratio.
• The maximum speed shall be referred to the motor specifications of the
appendix.
CAUTION
• Make sure to use the actual repetition frequency of the
motor smaller than the permitted repetition frequency
calculated on the above formula.
It shows the acceleration and deceleration of the motor in certain operation
