The Servo Drivers have internal regenerative energy absorption circuitry for absorbing
the regenerative energy produced during time such as Servomotor deceleration, and
thus preventing the DC voltage from increasing. An overcurrent error is generated, how-
ever, if the amount of regenerative energy from the Servomotor is too large. If this oc-
curs, measures must be taken to reduce the regenerative energy produced by changing
operating patterns, and so on, or to improve the regenerative energy absorption capac-
ity by connecting external regeneration resistance.
