System Design
Servo Drive Regeneration Absorption Capacity
Amount of Internal Regeneration Absorption in Servo Drives
This
Servo Drive
absorbs regenerative energy internally with built-in capacitors.
If the regenerative energy is too large to be processed internally, an overvoltage error occurs
and operation cannot continue.
The following table shows the regenerative energy (and amount of regeneration) that each
drive can absorb. If these values are exceeded, take the following processes.
Connect an External Regeneration Unit. (Regeneration process capacity improves.)
Reduce the operating rotation speed. (The amount of regeneration is proportional to the square
of the rotation speed.)
Lengthen the deceleration time. (Regenerative energy per unit time decreases.)
Lengthen the operation cycle, i.e., the cycle time. (Average regenerative power decreases.)
