5.2 Troubleshooting

POINT:Check the corresponding areas. If the cause is still unknown, it is

recommended to initialize the parameters (return to factory settings), re-set
the required parameter values, and check again.

5.2.1 Motor remains stopped

(1) Check the main circuit

Check that a proper power supply voltage is applied (control panel display
is provided).
Check that the motor is connected properly.
Check that the conductor across P1-+ is connected.

(2) Check the input signals

Check that the start signal is input.
Check that both the forward and reverse rotation start signals are not
input.
Check that the frequency setting signal is not zero.
Check that the AU signal is on when the frequency setting signal is 4 to
20mA.
Check that the output stop signal (MRS) or reset signal (RES) is not on.
Check that the sink/source connector is fitted securely.

(3) Check the parameter settings

Check that the reverse rotation prevention (Pr. 78) is not selected.
Check that the operation mode (Pr. 79) setting is correct.

Check that the bias and gain (Pr. 902 to Pr. 905) settings are correct.
Check that the starting frequency (Pr. 13) setting is not greater than the
running frequency.
Check that various operational functions (such as three-speed operation),
especially the maximum frequency (Pr. 1), are not zero.
Check that the manufacturer setting parameter Pr. 146 = 1.

(4) Check the load

Check that the load is not too heavy.
Check that the shaft is not locked.

(5) Others

Check that the ALARM lamp is off.

Check that the control panel display does not show an error (e.g. E.OC1).
Check that the Pr. 15 "jog frequency" setting is not lower than the Pr. 13
"starting frequency" value.

5.2.2 Motor rotates in opposite direction

Check that the phase sequence of output terminals U, V and W is correct.
Check that the start signals (forward rotation, reverse rotation) are connected
properly.
