TECO A510-2001-H - Auto-Tuning Error

5-11
5.4 Auto-tuning error
When the auto-tuning fault occurs, the fault of "AtErr" will be displayed on the digital
operator and the motor stops. The fault information is displayed on the 17-11. The fault
digital output contact does not act. Refer to Table 5.3, to identify and correct the faults.
Table 5.3 Auto-tuning fault and corrective actions
Error Description Cause Corrective action
01
Motor data input
error
· Input data error of
auto-tuning
·Error relationship between
the motor output current
and motor rated current
·Check the input data for
auto-tuning (17-00 to
17-09).
·Check the inverter
capacity
02
Tuning error of the
resistor R1 of motor
wire to wire.
03
Tuning error of motor
leakage inductance
04
Tuning error of motor
rotor resistance R2.
05
Tuning error of motor
mutual inductance Lm
07
Deadtime
compensation
detection
error
· Auto-tuning is not
completed within a certain
time
· Auto-tuning result is beyond
the parameter setting.
·Exceed the motor rated
current.
·Three phase output of the
inverter is broken off.
·Check the input data of
auto-tuning（17-00 to
17-09）
·Check motor connection.
·Disconnect all loads
connected to the motor.
·Check the inverter current
detection circuit,
including the current
sensor.
·Check motor connection.
·Check motor installation.
06 Motor encoder error
Motor encoder noise is too
large
Confirm the motor rated
current (02-01, 02-21).
08
Motor acceleration
error (only suitable
for the rotary type
auto-tuning).
Motor fails to accelerate in
specified time (00-14=
20sec).
· Increase the acceleration
time（00-14）.
· Disconnect all loads
connected to the motor.
09
Other errors of
auto-tuning
Other errors of auto-tuning
(except the ATE-01~ATE-08
error, such as the no load
current is higher than 70％,
rated current or torque
exceeds 100％ of the
reference).
· Check motor connection.
· Check the input data of
auto-tuning
