TECO A510-2001-H - PM Motor Auto-Tuning Error

5-12
5.5 PM motor auto-tuning error
When the PM motor auto-tuning fault occurs, the fault information of “IPErr” (PM motor
tuning failure) will be displayed on the digital operator and the motor stops. The fault
information is displayed on 22-18. The fault digital output contact does not act. Refer
to Table 5.4, to identify and correct the faults.
Table 5.4 Auto-tuning fault and corrective actions for PM motor
Error Description Cause Corrective action
01
Static magnetic pole
alignment failure
·Error relationship between
motor output current and
motor rated current.
·Check input data of
auto-tuning (22-02).
·Check the inverter
capacity
·Check Motor connection
02
Without PG option
card
· magnetic pole can not be
aligned without PG option
card
·Check PM’s PG card has
been installed properly or
not.
03
Rotary magnetic
pole alignment is
forced to stop.
·system abnormity
·Check it enters other
protection programs or
not.
04
Rotary magnetic
pole alignment is
time out
·Motor can not operate
properly.
·Check Motor connection
05
Circuit tuning is time
out
·System abnormity occurs in
circuit tuning process.
· Check it enters other
protection programs or
not.
06 Encoder error
·Motor encoder noise is too
large.
·Check PG card has been
grounded or not.
07
Other motor tuning
error
·Other errors of auto-tuning
·Check motor connection.
·Check input data of
auto-tuning
08
Current abnormity
occurs in rotary
magnetic pole
alignment.
·Motor can not operate at low
speed.
·it is possible that the
connections of PG card
A, B are reversal. It can
be redone. The system
will automatically adjust
the wiring definition.
·Check motor connection
09
Current abnormity
in circuit tuning.
· Error relationship between
motor output current and
motor rated current.
·Check input data of
auto-tuning (22-02).
·Check the inverter
capacity
10
Retry magnetic pole
alignment and
circuit tuning.
Auto-tuning is not
completion.
Retry magnetic pole
alignment and circuit
tuning.
