11. OPTIONS AND PERIPHERAL EQUIPMENT
11 - 10
Calculate the energy at different timings in one cycle. Energy is a positive value in power running and a
negative value in regeneration. Write down the energy during power running/regeneration with signs in
the calculation table as shown below.

Calculate the energy consumed by the regenerative resistor with the following equation for the
calculation results from E1 to E11 with a negative value.
When the absolute value of the value in E1 to E11 is assumed to be Es: ER [J] =
η
m
• Es - Ec
If ER values are negative at all timings, the regenerative option is not needed. If any of ER values is
positive, calculate the energy consumed by the regenerative resistor in one cycle from the time for one
cycle and the sum of the positive ER values.
PR [W] = Sum of the positive ER values/Operating time (tf) for one cycle
Regenerative option is not required when PR is equal to or less than the specification value of the servo
amplifier built-in regenerative energy.
