4. Power down the inverter and following safety
precautions, connect the motor. Power-up the
drive and repeat steps 1-3 and check the
following.
a. Is the direction of rotation correct?
b. Is the motor rotating smoothly with no
buzzing or abnormal vibration ?

c. Is the acceleration and deceleration smooth?
5. If no abnormalities are detected, increase the frequency and check the above items again.
If the results of the trial run are normal, proceed to start a formal run.
Note - If an error is detected in the above procedure immediately stop the operation and attempt to
determine the cause by referring to Chapter 7, Troubleshooting.
DANGER
Since voltage is still applied to the main circuit terminals (L1/R, L2/S, L3/T), and auxiliary
control power terminals (R0, T0) even when the output from the inverter is terminated, do not
touch the terminals. The large capacitor(s) in the inverter are still charged after the power is
turned off and do not discharge immediately. Before touching any electric circuit, confirm that
the charge lamp is off or a multimeter verifies that the voltage at the P-N terminals is below 25
VDC.
