Servo Drive Regeneration Absorption Capacity
The following table shows the regenerative energy (and amount of regeneration) that each
Servo Drive can absorb. If these values are exceeded, take the processes 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.
