124 Fault tracing
Code Error
4013 Hall sequence doesn't behave as
expected
(_ecHALL_FAULT_OR_NO_ROTA
TION)
4015 Position control update rate invalid
Cause
The Hall sequence doesn't
behave as expected. This error
can occur during the Test the
feedback test when using an
incremental encoder + Halls
feedback system.
Position loop control rate
(ControlRate(0, 1)) < 1.
What to do
The error can occur for a number of
reasons, so try the following tests:
•Return to the Confirm Motor
Information page of the Drive Setup
Wizard to check these values. If the
resolver is not a standard ABB
product, check that the specification
is compatible in the drives hardware
manual
•A common cause of this error is an
incorrectly wired or set up
encoder/resolver. Try manually
moving the rotor and watching the
position field in the Axis tab. If the
position does not change, or it
changes erratically, this indicates a
problem with the encoder wiring.
•Run the Test the feedback test
again. Ideally, the Test the feedback
test should be run with the motor
disconnected from the load, although
it will operate successfully where the
load is purely inertial or load friction is
small.
Note: watch the movement of the
rotor. For rotary motors, the shaft
should rotate through just over one
revolution in one direction followed by
one revolution in the opposite
direction. For linear motors, the rotor
should move through just over one
pole pitch in one direction followed by
one pole pitch in the opposite
direction. If the rotor moves
significantly more or less than these
distances, this indicates that the
number of motor poles is not set
correctly (rotary motors), or the pole
pitch is not set correctly (linear
motors). If the motion during the test
is not smooth, this indicates that
friction is high and the test will not be
able to obtain conclusive results.
Change control rate to expected
value (normally 4000)
