Troubleshooting Using the Operator Panel
If the motor does not start with the ON command:
• Check if Commissioning Parameter Filter P0010=0 (factory setting).
• Check if there is a valid ON signal.
• Check if Selection of Command Source parameter P0700=2 (for digital input control) or
P0700=1 (for BOP control).
Check if the correct setpoint is available (0 to 10V on terminal 3), or if the setpoint was entered in
the correct location in dependence of the setpoint source (Selection of Frequency Setpoint
parameter P1000). See the parameter list (see Appendix A in this document) for more detailed
information.
If the motor does not start after changing the parameters, set Commissioning Parameter Filter
P0010=30 (factory setting), set Parameter Reset P0970=1 (factory reset), and press P to reset
the SED2 to the factory-set parameter default values.
Use a switch between terminals 5 and 8 on the control terminal bar. The drive should now run
according to the default setpoint at the analog input.
NOTE: The voltage and current range of the SED2 must match the motor data.
Fault Codes
Error Cause Diagnosis/Remedy Reaction
F0001,
Overcurrent
• Motor power (P0307) is
greater than SED2
power (P0206).
• Motor lead short circuit.
• Earth faults.
Check the following:
• Motor power (P0307)
SED2 power (P0206).
• Cable length limits must not
be exceeded.
• Motor cable and motor must
not have short circuits or
earth faults.
• Motor parameters must
match the motor in use.
• Value of stator resistance
(P0350) must be correct.
• The motor must not be
obstructed or overloaded.
• Increase ramp-up time.
• Reduce boost level.
