WARNINGS
¾ Repairs on equipment may only be carried out by Siemens Service, by repair
centers authorized by Siemens or by authorized personnel who are
thoroughly acquainted with all the warnings and operating procedures contained
in this manual.
¾ Any defective parts or components must be replaced using genuine Siemens
authorized parts.
¾ Risk of electric shock. The DC link capacitors remain charged for five minutes
after power has been removed. It is not permissible to open the equipment
until 5 minutes after the power has been removed.
6.1 Troubleshooting with the Standard Inverter LED
The following is a description of the fault and warning indications given by the LED
on the Standard Inverter:
¾ Inverter Off/No supply: No LED lit.
¾ Power On/Ready: 200 ms On/800 ms Off
¾ Inverter Running OK: Steady LED
¾ General Warning: 800 ms On / 200 ms Off
¾ Fault Condition: 500 ms On / 500 ms Off
6.2 Troubleshooting with the BOP
If the display shows a fault or warning code, please consult the Faults and Warning
section of the SINAMICS G110 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 (see example on page 66).
¾ Check that P0700 = 1 (for BOP control) or
P0700 = 2 (for digital input control) or
P0700 = 5 (for USS input control – USS variant only)
P0719 is set to the correct Command and Frequency Setpoint.
¾ Check that the setpoint is present (0 to 10V on Terminal 9) 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 then:
1. Set P0010 = 30
2. Set P0970 = 1
3. Press
to reset the inverter to the factory default parameter values.
4. Use a switch between terminals 3 and 6 on the control board.
5. The inverter should now run to the setpoint defined by either the analogue
input or transmitted via the USS serial link communications.
NOTE
Motor data must relate to the inverter data power range and voltage.
