5-6-7 Selection of External Regenerative Resistor
When the Servo Motor is operating in the Generator Mode, the Electrical Energy will flow from
the Motor to the Driver, which is called Regenerative Power. The following conditions will enable the
Servo Motor to operate in the Generator (Regeneration) Mode:
(1) The period from deceleration to stop when the Servo Motor is operating in Acceleration /
Deceleration.
(2) When used to vertically load.
(3) When the Load End drives the Servo Motor in operation.
This regenerative power will be absorbed by the main circuit filter capacitor of the Driver, but when
there is excessive regenerative power and cannot be supported by the Filter Capacitor, Regenerative
Resistor must be used to consume excess regenerative power. The specification of built-in
regenerative resistor of this device is as follows:
