Observe the following precautions when connecting the external regenerative resistor:
● Remove the jumper between terminals P⊕ and D before using the external
regenerative resistor. Failure to comply will result in overcurrent and damage the
braking transistor.
● Do not connect the external regenerative resistor to the positive or negative pole
of the bus directly. Failure to comply will damage the servo drive and result in a
fire.
● Select a resistor with resistance higher than or equal to the minimum permissible
value. Failure to comply will result in Er.201 (Overcurrent) or damage the servo
drive.
● Make sure parameters H02‑25 (Regenerative resistor setting), H02‑26 (Power of
external regenerative resistor) and H02‑27 (Resistance of external regenerative
resistor) are set properly before operating the servo drive.
● Install the external regenerative resistor on an incombustible object such as a
metal.
