defective.
n
Motor control board
defective.
n
Incorrect speed control
parameters (Kv, Ki)
n
Incorrect speed control
filter parameters
n
Position module with
position encoder does
not exist.
n
Position module with
position encoder is not
correctly connected.
n
Position module with
position encoder is
defective.
n
PWM frequency within
an axis group is
incorrect.

module with position
encoder.
n
PWM frequency > 5 kHz only
with suitable hardware and
only with PWM output X51,
X52, X57 or X58
n
PWM frequency <= 5 kHz: For
the following PWM outputs,
the associated PWM
frequency entries must be
identical: 1) X51-X53-X54, 2)
X52-X55-X56, 3) X57-X59-X61,
or 4) X58
n
Entry must not be less than
3200; exception 0 corresponds
to 000
