Fault Message/Warning Cause Remedy
F137 Homing and feedback
mismatch
The configured homing mode is not
supported by the motor feedback
type used. Change homing mode.
F138 Instability during
autotune.
Drive current (IL.CMD) or velocity
feedback (VL.FB) exceeds allowable
limit. This fault only occurs in BODE.
MODE 5.
Change BODE.MODE if appropriate.
Otherwise the motor is not stable
and may require manual tuning.
F139
Target Position
over short due to
invalid motion task
activation.
The drive cannot decelerate from
its current speed to reach the end
point of the second motion task
without moving past it. Increase
the deceleration rate in the move or
trigger the move earlier
Change Motion task profile and
clear fault with DRV.CLRFAULTS,
or change the value of FAULT139.
ACTION = 1 to ignore this condition.
F140 VBUS.HALFVOLT has
changed.
The user changed the numerical
value of VBUS.HALFVOLT. The change
only takes effect after a DRV.NVSAVE
command and after rebooting the
AKD.
Save the parameters in the non-
volatile memory with DRV.NVSAVE
and turn off/on the 24[V] power
supply in order to reboot the drive
or restore the original setting of
VBUS.HALFVOLT.

F170
Motion task warning. Motion task settings and parameters
are not set to produce a valid motion
task.
DRV.CLRFAULTS will clear the
warning. Check motion task
settings and parameters to make
sure the values will produce a valid
motion task.
F201 Internal
RAM failed. Hardware failure detected. Restart drive. If issue persists,
contact technical support.
F202 External
RAM failed. Hardware failure detected. Restart drive. If issue persists,
contact technical support.
F203 Code integrity failed. Software failure detected. FPGA
register access failure occurred. Restart drive. If issue persists,
contact technical support.
F204
–
F232
EEPROM
failure detected. EEPROM failure detected. Restart drive. If issue persists,
exchange drive.
F234
–
F237
Control temperature
sensor high. Warning
issued prior to fault.
High temperature
limit reached. Check cabinet ventilation system.
F240
–
F243
Power temperature
sensor low. Warning
issued prior to fault.
Low temperature
limit reached. Check cabinet ventilation system.
F245 External fault. This fault is user generated and is
caused by user settings.
Users can configure a digital input
to trigger this fault (DINx.MODE =
10). the fault occurs according to
this input setting. Clear the input to
clear the fault.
