1.4 Selection of other accessories
1.4.1 Selection of regenerative resistance
When the servo motor is driven by the generator mode, the power returns to the servo amplifier side,
which is called regenerative power. The regenerated power is absorbed by charging the smooth
capacitor of the servo amplifier. After exceeding the rechargeable energy, the regenerative resistance is
used to consume the regenerative power.
The servo motor driven by regenerative (generator) mode is as follows:
The deceleration stop period during acceleration and deceleration operation;
Running vertically and axially;
When the external load drives the motor to rotate.

(1) Using built-in regenerative resistance, short P + and D terminals, P + and
C are disconnected.
(2) Use external regenerative resistance, connect regenerative resistance to P
+ and C terminals, remove P + and D short wiring, P0-25 = power value,
P0-26 = resistance value.
Note: if software version U2-07 < 3700, the parameter P0-24 should be set.
The value of 0 is for the built-in resistance to take effect, and the value of 1 is
for the external resistance to take effect.
The following table is the recommended specifications of external regenerative resistance for each type
of motor.

Note:
(1) The smaller the resistance is, the faster the discharge will be, but the smaller the resistance is, the
easier the breakdown resistance will be. Therefore, please close to the the lower limit but not be less
than the lower limit when choosing the type.
(2) When wiring, please use high-temperature flame-retardant wire, and the regenerative resistance
surface can not contact with the wire.
