Servo Drive Regenerative Energy Absorption Capacity
Amount of Internal Regeneration Absorption in Servo Drives
The OMNUC G-Series Servo Drives absorb 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 Servo Drive can absorb.
If these values are exceeded, take the following measures.
• Connect an External Regeneration Resistor (to improve the regeneration processing capacity).
• Reduce the operating rotation speed. (The amount of regeneration is proportional to the square of
• Lengthen the deceleration time (to decrease the regenerative energy produced per time unit).
• Lengthen the operation cycle, i.e., the cycle time (to decrease the average regeneration power).
Note These are the values at 100 VAC for 100-VAC models, and at 200 VAC for 200-VAC models.
