0026
AUTOPHASING
(0x3187)
Autophasing routine failed
because the estimated angle of
the rotor differs too much from
the measured angle of the rotor.
All other reasons for the
autophasing fault are explained
in section
on page
Try other autophasing modes (see parameter
) if possible.
In addition, repeat autophasing multiple times
and check the value in parameter
between separate runs (see
section
). The value should not
change between consecutive autophasing
runs.
Check that there is no slip in the encoder
connection to the motor axle. Because of the
slip the estimated and measured drive speed
may differ during fast accelerations/
decelerations.
0027
PU LOST
(0x5400)
Connection between the JCU
Control Unit and the power unit
of the drive is lost.
Check the connections between the JCU
Control Unit and the power unit.
If the JCU is powered from an external
supply, ensure that parameter
is set to
.
0028
PS COMM
(0x5480)
Communication errors detected
between the JCU Control Unit
and the power unit of the drive.
Check the connections between the JCU
Control Unit and the power unit.
If the JCU is powered from an external
supply, ensure that parameter
is set to
.
0029
IN CHOKE TEMP
(0xFF81)
Temperature of internal AC
choke excessive.
Check cooling fan.
0030
EXTERNAL
(0x9000)
Fault in external device. (This
information is configured
through one of programmable
digital inputs.)
Check external devices for faults.
Check setting of parameter
.
0031
SAFE TORQUE OFF
(0xFF7A)
Programmable fault:
Safe Torque Off function is
active, i.e. safety circuit
signal(s) connected to
connector X6 is lost
- during drive start or drive run
or
- while drive is stopped and
parameter
Check safety circuit connections. For more
information, see the appropriate drive
hardware manual and
Application guide -
Safe torque off function for ACSM1, ACS850
and ACQ810 drives
(3AFE68929814
[English]).
0032
OVERSPEED
(0x7310)
Motor is turning faster than
highest allowed speed due to
incorrectly set minimum/
maximum speed, insufficient
braking torque or changes in
load when using torque
reference.
Check minimum/maximum speed settings,
parameters
and
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for braking chopper and
resistor(s).
