DRIVE
WARNING
F15
Theoretical drive temperature,
due to provided current to load,
exceeded maximum threshold.
Drive continuous to operate nor-
mally, but maximum provided cur-
rent is equal to drive rated current.
During initial start-up, please ensu-
re a correct motor and drive wiring.
Ensure that working cycle to be per-
formed is not too much hard for se-
lected drive.
Ensure that control loop parameters
(speed) are not heavy.
If application allows, increase ramp
times.
YES
NO
I2T
MOTOR
WARNING
F16
Theoretical motor temperature,
due to provided current from dri-
ve, exceeded maximum 100°C ΔT
threshold.
Drive continuous to operate nor-
mally, but maximum provided
current is equal to motor rated
current.
Ensure that working cycle to be per-
formed is not too much heavy for
used motor.
Ensure that control loop parameters
(speed) are not heavy.
If application allows, increase ramp
times.
Ensure that ‘I2T Time’ value, set in
Motor Data section via Caliper, is
correct for used motor.
YES
NO

SPEED
WARNING
F17
Maximum velocity value, set in
Advanced Setup - Limiter section
via Caliper, exceeded threshold.
Drive continuous to operate nor-
mally, showing warning condition.
Please ensure that ‘Speed Limit’ pa-
rameter is at least 10% upper than
maximum reachable speed.
Ensure that speed loop parameters
do not generate high speed over-
shoot.
YES
NO
CH1
STO
FA18 Redundant n°1 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
TARGET
OUTSIDE
WARNING
F19
During position control, drive has
detected that position reached is
different to target position.
Drive continuous to operate nor-
mally, showing warning condition.
Drive received an external signal and
has been stopped during positio-
ning; for this reason it was not able
to reach target position.
Verify if commands sent to drive are
OK
YES
NO
FIELDBUS
FA20 Canopen® Node Guarding error
occures or Time out error Modbus
occures.
Drive stops providing current and
‘Drive OK’ condition is disabled.
Depending on settings, drive
stops providing current or decele-
rates in ramp.
Restore fieldbus comunication.

FA21 EEPROM memory does not re-
spond.
Drive stops.
A repair from technical and designa-
ting person is required.
