4-5-2 Servo Drive Regeneration Absorption Capacity
The following table shows the regenerative energy (and amount of regeneration) that each drive can
absorb. If these values are exceeded, take the processes described above.
Regenerative energy to be absorbed by built-in capacitor varies depending on the input voltage to the
main circuit power supply for the Servo Drive. The above value for each Servo Drive model is calculated
when the input voltage is as follows.
