acceleration in the negative direction is shown as negative.
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 overvoltage error is generated,
however, if the amount of regenerative energy from the Servomotor is too large. If this
occurs, measures must be taken to reduce the regenerative energy produced by
changing operating patterns, and so on, or to improve the regenerative energy
absorption capacity by connecting external regeneration resistance.
