(1)
Load Loss 2 The output torque current is below the
value programmed in
A490 [Load Loss
Level] for a time period greater than the
time programmed in
A491 [Load Loss
Time].
• Verify connections between motor
and load.
• Verify level and time requirements
F021 Output Ph Loss 1 Output Phase Loss (if enabled).
Configure with
A557 [Out Phas Loss En].
• Verify motor wiring.
• Verify motor.
F029 Analog In Loss 1 An analog input is configured to fault on
signal loss. A signal loss has occurred.
Configure with
t094 [Anlg In V Loss] or
t097 [Anlg In mA Loss].
• Check for broken/loose connections
at inputs.
• Check parameters.
F033 Auto Rstrt Tries 2 Drive unsuccessfully attempted to reset
a fault and resume running for the
programmed number of
A541 [Auto
Rstrt Tries].
Correct the cause of the fault and
manually clear.
F038 Phase U to Gnd 2 A phase to ground fault has been
detected between the drive and motor
in this phase. • Check the wiring between the drive
and motor.
• Check motor for grounded phase.
• Replace drive if fault cannot be
cleared.
F039 Phase V to Gnd
F040 Phase W to Gnd
F041 Phase UV Short 2 Excessive current has been detected
between these two output terminals. • Check the motor and drive output
terminal wiring for a shorted
condition.
• Replace drive if fault cannot be
cleared.
F042 Phase UW Short
F043 Phase VW Short
F048 Params Defaulted 1 The drive was commanded to write
default values to EEPROM. • Clear the fault or cycle power to the
drive.
• Program the drive parameters as
needed.
F059 (1) Safety Open 1 Both of the safety inputs (Safety 1,
Safety 2) are not enabled.
Configure with
t105 [Safety Open En].
• Check safety input signals. If not
using safety, verify and tighten
jumper for I/O terminals S1, S2 and
S+.
F063 SW OverCurrent 1 Programmed A486 , A488 [Shear Pinx
Level] has been exceeded for a time
period greater than the time
programmed in
A487 , A489 [Shear Pin x
Time].
• Verify connections between motor
and load.
• Verify level and time requirements.
F064 Drive Overload 2 Drive overload rating has been
exceeded. Reduce load or extend Accel Time.
F070 Power Unit 2 Failure has been detected in the drive
power section. • Check maximum ambient
temperature has not been exceeded.
• Cycle power.
• Replace drive if fault cannot be
cleared.
F071 DSI Net Loss 2 Control over the Modbus or DSI
communication link has been
interrupted. • Cycle power.
• Check communications cabling.
• Check Modbus or DSI setting.
• Check Modbus or DSI status.
F072 Opt Net Loss 2 Control over the network option card’s
remote network has been interrupted. • Cycle power.
• Check communications cabling.
• Check network adapter setting.
• Check external network status.
F073
(1)
EN Net Loss 2 Control through the embedded
EtherNet/IP adapter has been
interrupted. • Cycle power.
• Check communications cabling.
• Check EtherNet/IP setting.
• Check external network status.
F080 Autotune Failure 2 The autotune function was either
cancelled by the user or failed. Restart procedure.
