Servo Drive Regeneration Absorption Capacity

Amount of Internal Regeneration Absorption in Servo Drives
This
Servo Drive
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 Resistor. (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.)
