Trips and Fault Finding
Possible Reason for Trip
DOUT2 overload on terminal 10:
 50mA maximum
Unknown trip
"OTHER" trip is active (Trip ID 34 to 44 inclusive)
During Autotune the motor is required to run at the
nameplate speed of the motor. If MAX SPEED RPM limits the
speed to less than this value, an error will be reported.
Increase the value of MAX SPEED RPM up to the nameplate
rpm of the motor (as a minimum). It may be reduced, if
required, after the Autotune is complete.
Autotune. Re-try when the mains has recovered.
The motor was unable to reach the required speed to carry
out the Autotune. Possible reasons include:

motor shaft not free to turn

the motor data is incorrect
It was not possible to find a suitable value of magnetising
current to achieve the required operating condition for the
motor. Check the motor data is correct, especially
nameplate rpm and motor volts. Also check that the motor is
correctly rated for the drive.
Autotune has calculated a negative slip frequency, which is
not valid. Nameplate rpm may have been set to a value
higher than the base speed of the motor. Check nameplate
rpm, base frequency, and pole pairs are correct.
The calculated value of rotor time constant is too large.
Check the value of nameplate rpm.
The calculated value of rotor time constant is too small.
Check the value of nameplate rpm.
This error is reported when the MAX SPEED RPM is set to a
value outside the range for which Autotune has gathered
data. Autotune gathers data on the motor characteristics up
to 30% beyond "max speed rpm". If MAX SPEED RPM is later
increased beyond this range, the drive had no data for this
new operating area, and so will report an error. To run the
motor beyond this point it is necessary to re-autotune with
MAX SPEED RPM set to a higher value.
The motor must be stationary when starting the Autotune
The motor must be able to rotate during Autotune
to be inserted into the motor. It has not been possible to
achieve the required level of current. Check that the motor is
wired correctly.
