4-4 Regenerative Energy Absorption

System Design
• For Servo Drive models with internal capacitors used for absorbing regenerative energy (i.e.,
models of 400 W or less), the values for both E
g1
or E
g2
(unit: J) must be lower than the Servo
Drive’s regenerative energy absorption capacity. (The capacity depends on the model. For details,
refer to Servo Drive Regenerative Energy Absorption Capacity on page 4-48.)
• For Servo Drive models with an internal regeneration resistor used for absorbing regenerative
energy (i.e., models of 500 W or more), the average amount of regeneration Pr (unit: W) must be
calculated, and this value must be lower than the Servo Drive’s regenerative energy absorption
capacity. (The capacity depends on the model. For details, refer to Servo Drive Regenerative
Energy Absorption Capacity on page 4-48.)
The average regeneration power (Pr) is the regeneration power produced in one cycle of
operation.
Pr = (Eg1 + Eg2) / T [W]
T: Operation cycle [s]
