• 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 parame-
ter 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 F004, 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 parameters 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.
• Alarm LED – ON when the inverter in Trip Mode.
• 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 [PCS],
[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 SJ200 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.

Parameter tables for user-settable functions follow these conventions:
• Some parameters have 2nd motor equivalents, indicated by the x2xx
parameter codes in the left-most column.
• Some parameters specify an option code. Where applicable, the
options codes will be in a bulleted list in the Name/Description
column.
• The default values apply to all models unless otherwise noted for each
parameter... –FEF (Europe) / – FU (USA)
• Some parameters cannot be edited during Run Mode, and certain
Software Lock settings (B031) can prohibit all edits. If in doubt, place
the inverter in Stop Mode or consult the inverter manual for details.
