Protective Functions
The SJ100 series inverter will trip on overcurrent, overvoltage and undervoltage to protect the
inverter.The output is shut down and the motor runs free. This condition is held until it is reset.
Trip Contents
Overcurrent When the output of the inverter is short circuited,
protection the motor is locked, or a heavy load is suddenly
applied, and the inverter output current exceeds a
predetermined level, the inverter is shut off.
Overload When a motor overload is detected by the electronic
protection thermal function, the inverter is shut off.
Braking resis- When regenerative braking resistor exceeds the usage
tor overload time duration an overvoltage caused by the stop of the
BRD function is detected, and inverter output is cut off.
Overvoltage When the inverter DC bus voltage exceeds a pre-
protection determined level due to regenerative energy from the
motor, this trip occures and the inverter is shut off.
EEPROM error When the inverter memory has a problem due to
(NOTE 1) noise or excessive temperature rise, this trip occurs
and the inverter is shut off.
Undervoltage A decrease of DC bus voltage may result in improper
protection function of the control unit. It may also cause motor
heating and low torque. The inverter is shut off when
the DC bus voltage goes below a certain level.
CT error When a large noise source is near the inverter or an
abnormality occurs on built-in CT, inverter output is
cut off.
CPU error Malfunction or abnormality of the CPU. The inverter
is shut off.
External trip A trip signal from external equipment shuts off the
inverter. It is necessary to assign the external trip to
an intelligent terminal.
USP error Indicates an error when power is turned on while the
inverter run is enabled (with USP function selected).
Ground fault The inverter is protected by detection of ground
protection faults between the drive output and the motor at
power on. Protection is for the inverter only and not
for humans.
Input When the input voltage is higher than a specified
overvoltage value, it is detected and 100 seconds after power is
turned on, the inverter is shut off.
Short power A short input voltage interruption (>15ms) occured.
down The inverter is shut off.
Error in link to There is an error in the link to the extension card in
option 1 slot 1 (2). The inverter is shut off.
(option 2)
Error option 1 There is an error in the extension card in slot 1 (2).
(option 2) The inverter is shut off.
Phase failure One of the power supply phases has broken down.
The inverter is shut off.
J300 data setting values J300 inverters provide many functions whose parameters can be
set by the user. It is recommended that the parameters that have been set by the user be recorded
in order to speed the
investigation and re- J300
pair in the event of
a failure.
