Error Codes
The SJ200
series inverters will trip on over-current, over-voltage, and
2
under-voltage to protect the inverter. The motor output turns OFF, allow-
ing the motor to free-run to a stop. Press the Stop/Reset key to reset the
inverter and clear the error.

Name
Probable Cause(s)
• Inverter output was short-circuited
• Motor shaft is locked
• Load is too heavy
• A dual-voltage motor is wired
incorrectly
Note: The SJ200
nominally 200% of rated current
• DC braking power(A054) set too high
• Current transformer / noise error
• Motor overload is detected by the
electronic thermal function
• Regenerative braking resistor exceeds
the usage time or usage ratio
• DC bus voltage exceeds a threshold,
due to regenerative energy from motor
• Built-in EEPROM memory experi-
enced noise, high temperature, etc.
• DC bus voltage decreased enough to
cause a control circuit fault
• Built-in CPU had internal error
• [EXT] input signal detected
• When (USP) was enabled, an error
occurred when power was applied while
a Run signal was present
• A ground fault was detected between
the inverter output and the motor. This
feature protects the inverter, and does not
protect humans.
• Input voltage was higher than specified
value, after 60 sec. in Stop Mode
• Inverter internal temperature is above
the threshold
