REACT.
MOTOR
PHASES
F22
During motor autophasing, drive
has detected a wrong wiring con-
nection.
If SWITCH-ON command is able,
motor could run without control.
Depending on used motor, recom-
mended solutions are:
• H.D.T. motor: ensure the correct
wiring between drive and motor,
then execute motor autophasing.
See
“5.02 J1 connector: motor power
.
• Third party motor: invert 2 motor
phases, then execute motor
autophasing.
YES
NO
CH2
STO
FA23 Redundant n°2 channel of safety
circuit is broken.
If external environment cable is cor-
rectly set, a repair from technical and
designating person is required.
NO
NO
OVER
TEMP.
FA24 Heatsink temperature exceeded
maximum threshold.
Drive stops providing current and
‘Drive OK’ condition is disabled.
Recommended solutions:
• wait some minutes before
restarting drive.
• ensure ambient temperature to be
lower than 40°C.
YES
NO
HALL
ENSORS
SEQUENCE
ERROR
FA25 Drive detected a wrong HALL se-
quence.
Drive stops providing current and
‘Drive OK’ condition is disabled.
Recommended solutions:
• connect correctly HALL sensors.
YES
NO
SPEED
ERROR
FA26 In Canopen mode, in profile velo-
city mode, drive detected a speed
error depending on velocity win-
dow and velocity window time
parameters.
Drive stops providing current and
‘Drive OK’ condition is disabled.
Recommended solutions:
• increase velocity window and
velocity window time parameters.
• if application allows, decrease
acceleration and deceleration
ramp parameters.
• ensure that there are not any
barriers or obstacles during
movement.
YES
NO
I2T
DRIVE
ALARM
FA27 Theoretical drive temperature,
due to provided current to motor,
exceeded maximum threshold
and drive continued to provide
current beyond set time.
Drive stops providing current and
‘Drive OK’ condition is disabled.
During initial start-up, please ensure
a correct motor and drive wiring.
Ensure that there are no obstacles
along the axis stroke.
YES
NO
I2T
MOTOR
ALARM
FA28 Theoretical motor temperature,
due to provided current from dri-
ve, exceeded maximum 100°C ΔT
threshold and drive continued to
provide current beyond set time.
Drive stops providing current and
‘Drive OK’ condition is disabled.
Ensure that working cycle to be per-
formed is not too much heavy for
used motor.
YES
NO
DC BUS
SYMMETRY
FA29 Drive has detected that DC bus
symmetry is out of range.
Drive stops providing current and
‘Drive OK’ condition is disabled.
Disconnect power supply by the dri-
ve immediatly.
A repair from technical and designa-
ting person is required.
