code
Reversed motor phases when operating
with feedback or reversed encoder
tracks so that the direction of rotation
has changed
z Check the motor cable connection for
correct phase position
z If possible, operate the motor with
deactivated feedback (C0025 = 1) and
check the direction of rotation of t he
motor.

z Use a braking unit or regenerative
module
z When using the braking units 935x,
check the settings of the switching
thresholds (see Operating
Instructions for 9350 braking unit)
z In case of parallel connection of 935x
braking units, check the settings for
master and slave (see Operating
Instructions for 9350 braking unit)
z If possible prolong the braking ramp
(C0013, C0105)
PEr x074 Program fault An error has been detected in the
program run. The parameter set 1 is
loaded automatically. All parameter
data which have been changed before
but not saved will get lost.
