Cause
Troubleshooting
Solution
1. The external regenerative
resistor is connected
improperly or disconnected.
Remove the external
regenerative resistor and
measure whether its
resistance is "∞" (infinite).
Measure whether the
resistance between
terminals P⊕ and C is "∞"
(infinite).
Replace with a new external
regenerative resistor. After
confirming the resistance
measured is the same as the
nominal value, connect it
between terminals P⊕ and
C.
Connect the external
regenerative resistor
between terminals P⊕ and
C with a proper cable.
2. The jumper between
terminals P⊕ and D is
shorted or disconnected
when the built‑in
regenerative resistor is used.
Measure whether the
resistance between
terminals P⊕ and D is "∞"
(infinite).
Ensure terminals P⊕ and D
are jumpered.
3. H02.25 (Regenerative
resistor type) is set
improperly when an external
regenerative resistor is used.
● Check the setpoint of
H02.25.
● Measure the resistance of
the external regenerative
resistor connected
between P⊕ and C. Check
whether the resistance
measured is too large by
comparing it with the value
listed in Table
"Specifications of the
regenerative resistor".
● Check whether the value of
H02.27 is larger than the
resistance of the external
regenerative resistor
connected between
terminals P⊕ and C.
Set H02.25 according to
section Wiring and Setting of
Braking Resistor in the
Hardware Guide.
H02.25 = 1 (external,
naturally ventilated)
H02.25 = 2 (external, forced‑
air cooling)
4. The resistance of the
external regenerative
resistor is too large.
Select a proper regenerative
resistor according to section
"Specifications of the
Regenerative Resistor" in
SV660F Series Servo Drive
Commissioning Guide.
5. The setpoint of H02.27
(Resistance of external
regenerative resistor) is
higher than the resistance of
the external regenerative
resistor used.
Set H02.27 according to the
resistance of the external
regenerative resistor used.
