Troubleshooting and Diagnostics
Fault Cause
Remedy
(1)
f.HF High DC Bus Voltage
fault
Mains voltage is too high Check mains voltage and P107
Decel time is too short, or too
much regen from motor
Increase active decel time
(P105, P126, P127) or install
Dynamic Braking option
f.1L
Digital Input
Configuration fault
(P121...P123)
More than one digital input set for
the same function
Each setting can only be used
once (except settings 0 and 3)
Only one digital input configured
for MOP function (Up, Down)
One input must be set to MOP Up,
another must be set to MOP Down
PID mode is entered with setpoint
reference and feedback source
set to the same analog signal
Change PID setpoint reference
(P121…P123) or feedback source
(P201).
One of the digital inputs (P121…
P123) is set to 10 and another is
set to 11…14.
Reconfigure digital inputs
One of the digital inputs (P121…
P123) is set to 11 or 12 and
another is set to 13 or 14.
PID enabled in Vector Torque mode
(P200 = 1 or 2 and P300 = 5)
PID cannot be used in Vector
Torque mode
f.JF
Remote keypad fault Remote keypad disconnected Check remote keypad connections
f.LF
Low DC Bus Voltage fault Mains voltage too low Check mains voltage
f.n1d
No Motor ID fault An attempt was made to start the
drive in Vector or Enhanced V/
Hz mode prior to performing the
Motor Auto-calibration
See P300…P399 for Drive Mode
setup and calibration.
f.ntF
Module communication
fault
Communication failure between
drive and Network Module.
Check module connections
f.nF1
…
f.nF9
Network Faults Refer to the module documentation.
for Causes and Remedies.
f.OF
Output fault:
Transistor fault
Output short circuit Check motor/motor cable
Acceleration time too short Increase P104, P125
Severe motor overload, due to:
• Mechanical problem
• Drive/motor too small for
application
• Check machine / system
• Verify drive/motor are proper
size for application
Boost values too high Decrease P168, P169
Excessive capacitive charging
current of the motor cable
• Use shorter motor cables with
lower charging current
• Use low capacitance motor
cables
• Install reactor between motor
and drive.
Failed output transistor Contact factory technical support

The drive can only be restarted if the error message has been resent.
