RUN
After the data has
been changed,
press the FUNC
key to save data.
[FUNC key] ... This key switches
between the parameter area, data
area, and extended function area.
Each time the key is pressed, the
display changes as follows:
[UP key, DOWN key] ... These keys change the
values of data area, and parameters:
[START key] ... This key
starts the J300 inverter.
Set forward or reverse
run using
F 4
.
[STOP key] ... This key
stops the J300 inverter.
When a trip occurs, this key

Overcurrent
protection
When the output of the inverter is short circuited,
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
protection
When a motor overload is detected by the electronic
thermal function, the inverter is shut off.
E05
Braking resis-
tor overload
When regenerative braking resistor exceeds the usage
time duration an overvoltage caused by the stop of the
BRD function is detected
,
and inverter out
p
ut is cut off.
E06
Overvoltage
protection
When the inverter DC bus voltage exceeds a pre-
determined level due to regenerative energy from the
motor, this trip occures and the inverter is shut off.
E07
EEPROM error
(NOTE 1)
When the inverter memory has a problem due to
noise or excessive temperature rise, this trip occurs
and the inverter is shut off.
E08
Undervoltage
protection
A decrease of DC bus voltage may result in improper
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.
E09
CT error When a large noise source is near the inverter or an
abnormality occurs on built-in CT, inverter output is
cut off.
E10
CPU error Malfunction or abnormality of the CPU. The inverter
is shut off.
E11
External trip A trip signal from external equipment shuts off the
inverter. It is necessary to assign the external trip to
an intelligent terminal.
E12
USP error Indicates an error when power is turned on while the
inverter run is enabled
(
with USP function selected
)
.
E13
Ground fault
protection
The inverter is protected by detection of ground
faults between the drive output and the motor at
power on. Protection is for the inverter only and not
for humans.
E14
Input
overvoltage
When the input voltage is higher than a specified
value, it is detected and 100 seconds after power is
turned on, the inverter is shut off.
E15
Short power

A short input voltage interruption (>15ms) occured.
The inverter is shut off.

Protective Functions
The SJ100 series inverter will trip on overcurrent, overvoltage and undervoltage to protect th
e
inverter.The output is shut down and the motor runs free. This condition is held until it is reset.
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

1: If an EEPROM error occurs, be sure to observe ist value. If power is turned off while the
[RS] input terminal is held ON, the EEPROM error occurs when power is turned back on.
