8 Basic Wiring Dia gram The following wiring diag ram show s the power and motor connections for basic operation. The op tional signal input wiring supports e xternal Fwd and Rev Run command, an d a speed potentiome ter .
9 In verter Ke ypad Operation • Run/Stop LED – ON when the inv erter output is ON and the motor is de veloping torque , and OFF when the in verter ou tput is OFF (Stop Mode). • Program/Monitor LED – ON when the inv erter is ready for parame- ter editing (Program Mode).
10 • Para meter Disp lay – A 4-digit, 7-segment display for parameter s and function codes. • Display Units: Hertz/Amperes – One of these LEDs will be O N to indicate the units associated with the parameter display . • Po wer LED – ON when the power input to the inv erter is ON.

12 P o werup T est The Powerup T est procedure uses mi nimal parameter settings to run the motor . The procedur e describes two alternati ve methods for command ing the in verter: via the in verter ke ypad , or via the logic terminals . • Check power input and m otor output wiring (see page 8 diagram) .
13 Error Codes The SJ200 2 series in v erters will trip on over-current, ov er-v oltage, and under-v oltage to protect the in v erter . The motor output turns OFF , allow- ing the motor to free-run to a stop. Pr ess the Stop/Reset key to reset the in verter and clear the error .
