ATN 3 NOT AT SPEED
♦ 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
ATN4 MAG CURRENT
FAIL
♦ It was not possible to find a suitable value of
magnetizing 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.
ATN5 NEGATIVE SLIP F
♦ 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.
ATN6 TR TOO LARGE
♦ The calculated value of rotor time constant is too
large. Check the value of nameplate rpm.
ATN7 TR TOO SMALL
♦ The calculated value of rotor time constant is too
small. Check the value of nameplate rpm.
