Inverter Keypad Operation
•Run/Stop LED – ON when the inverter output is ON and the
motor is developing torque, and OFF when the inverter output is
OFF (Stop Mode).
•Program/Monitor LED – ON when the inverter is ready for
parameter editing (Program Mode). It is OFF when the parameter
display is monitoring data (Monitor Mode).
•Run Key Enable LED – ON when the inverter is ready to
respond to the Run key, OFF when the Run key is disabled.
•Run Key – Press this key to run the motor (the Run Enable LED
must be ON first). Parameter F_04, Keypad Run Key Routing,
determines whether the Run key generates a Run FWD or Run
REV command.
•Stop/Reset Key – Press this key to stop the motor when it is
running (uses the programmed deceleration rate). This key will
also reset an alarm which has tripped.

•Potentiometer – Allows an operator to directly set the motor
speed when the potentiometer is enabled for output frequency
control.
•Potentiometer Enable LED – ON when the potentiometer is
enabled for value entry.
•Parameter Display – A 4-digit, 7-segment display for parame-
ters and function codes.
•Display Units: Hertz/Amperes – One of these LEDs will be ON
to indicate the units associated with the parameter display.
•Power LED – ON when the power input to the inverter is ON.
•Function Key – This key is used to navigate through the lists of
parameters and functions for setting and monitoring parameter
values.
•Up/Down Keys – Use these keys alternately to move up or down
the lists of parameter and functions shown in the display, and to
increment/decrement values.
•Store Key – When the unit is in Program Mode and the operator
has edited a parameter value, press the Store key to write the new
value to the EEPROM.

Powerup Test
The Powerup Test procedure uses minimal parameter settings to run
the motor. The procedure describes two alternative methods for
commanding the inverter: via the inverter keypad, or via the logic
terminals.
• Check power input and motor output wiring (see page 4 diagram).
• If using logic terminals for testing, verify correct wiring on [P24],
[FW], [H], [O], and [L] (bottom row) per the diagram on page 4.
• Reverse [RV] input wiring (defaults to terminal [2]) is optional.

Error Codes
The SJ100 series inverters will trip on over-current, over-voltage,
and under-voltage to protect the inverter. The motor output turns
OFF, allowing the motor to free-run to a stop. Press the Stop/Reset
key to reset the inverter and clear the error.
Basic Error Codes
Error
Code Name Probable Cause(s)
E01 Over current event while
at constant speed
• Inverter output was short-circuited
• Motor shaft is locked
• Load is too heavy
• A dual-voltage motor is wired
incorrectly
Note: The SJ100 will over current trip
at nominally 200% of rated current
E02 Over current event during
deceleration
E03 Over current event during
acceleration
E04 Over current event for
other conditions
• DC braking power(A_54) set too
high
• Current transformer / noise error
E05 Overload protection • Motor overload is detected by the
electronic thermal function
E06 Braking resistor overload • Regenerative braking resistor
exceeds the usage time or usage ratio
E07 Over voltage protection • DC bus voltage exceeds a threshold,
due to regenerative energy from motor
E08 EEPROM error • Built-in EEPROM memory experi-
enced noise, high temperature, etc.
E09 Under-voltage error • DC bus voltage decreased enough to
cause a control circuit fault
E10 CT error
(current transformer)
• High electrical noise near inverter
• A fault occurred in the built-in CT
E11
E22
CPU error • Built-in CPU had internal error
E12 External trip • [EXT] input signal detected
E13 USP (Unattended Start
Protection)
• When (USP) was enabled, an error
occurred when power was applied
while a Run signal was present
E14 Ground fault • A ground fault was detected
between the inverter output and the
motor. This feature protects the
inverter, and does not protect humans.
