4. The resistance of the
regen resistor is too
large, and the energy
absorption during braking
is insufcient.
•
Measure the resistance of the
external regen resistor between
P and C. Compare the measured
value with the recommended value.
•
Connect a new external
regen resistor of the
recommended resistance
between P and C.
•
Make H02-26(Power of
external regen resistor)
and H02-27 (Resistance
of external regen resistor)
consistent with the used
external regen resistor
specication.
5. The motor is in abrupt
acceleration/deceleration
state. The maximum
braking energy exceeds
the energy absorption.
•
Conrm the acceleration/
deceleration time during running
and measure the DC bus voltage
between P and
-
. Check
whether the voltage exceeds the
fault level during deceleration.
First, ensure that the input
voltage of the main circuit
is within the specication.
Then increase/decrease the
acceleration/deceleration time
in the allowed range.
6. The bus voltage
sampling value has a
large deviation from the
actually measured value
•
Check whether H0B-26 (bus
voltage) is within the following
specication:
220 V drive: H0B-26 > 420 V
380V drive: H0B-26 > 760 V
Measure the DC bus voltage
between P and
-
. Check
whether the DC bus voltage is
normal and smaller than H0B-26.

7.The servo drive is
faulty.
•
The fault remains after the main
circuit is powered off and re-
powered on several times.
Replace the servo drive.
