4.2 Troubleshooting with the BOP
Warnings and faults are displayed on the BOP with Axxx and Fxxx respectively.
The individual messages are shown in the Parameter list.
If the motor fails to start when the ON command has been given:
¾ Check that P0010 = 0.
¾ Check that a valid ON signal is present.
¾ Check that P0700 = 2 (for digital input control) or
P0700 = 1 (for BOP control).
¾ Check that the setpoint is present (0 to 10V on Terminal 3) or the setpoint has
been entered into the correct parameter, depending upon the setpoint source
(P1000). See the Parameter List for further details.
If the motor fails to run after changing the parameters, set P0010 = 30 then P0970
= 1 and press P to reset the inverter to the factory default parameter values.
Now use a switch between terminals 5 and 9 (Figure 3-14). The drive should now
run to the defined setpoint by analogue input.
NOTICE
Motor data must relate to the inverter data power range and voltage.
