More than one digital input is set for
the same function.
Each setting can be used once
(except settings 0 and 3).
Only one digital input is configures
for the MOP function (Up, Down).
One input must be set to MOP Up,
and another must be set to MOP
Down.
PID mode is entered with the
setpoint reference and feedback
source set to the same analog
signal.
Change the PID setpoint reference
(P121–P124) or feedback source
(P201).
One of the digital inputs
(P121–P124) is set to 10 and
another is set to 11–14.
Reconfigure the digital inputs.
One of the digital inputs
(P121–P124) is set to 11 or 12
and another is set to 13 or 14.
Reconfigure the digital inputs.
F_IL
Digital Input
Configuration
(P121–P124)
PID is enabled in Vector Torque
mode (P200=1 or 2 and P300=5).
PID cannot be used in Vector
Torque mode.
F_JF
Remote Keypad
The remote keypad is disconnected.
Check the remote keypad
connections.
F_LF
Low DC Bus
Voltage
The mains voltage is too low.
Check the mains voltage.
F_nId
No Motor ID
An attempt was made to start the
drive in Vector or Enhanced V/Hz
mode before performing the Motor
Auto-calibration.
Refer to parameters P300–P399 for
Drive Mode setup and calibration.
F_ntF
Module
Communication
Communication failure between the
drive and the network module.
Check the module connections.
F_nF1
through
F_nF9
Network
Refer to the module documentation for causes and remedies.
Output short circuit.
Check the motor and motor cable.
Acceleration time was too short.
Increase P104 and P125.
Severe motorload due to a
mechanical problem or the
drive/motor is too small for the
application.
• Check the machine and the
system.
• Verify that the drive and motor are
the proper size for the application.
Boost values are too high.
Decrease P168 and P169.
Excessive capacitive charging
current of the motor cable.
• Use shorter motor cables with
lower charging current.
• Use low capacitance motor
cables.
• Install a reactor between the
motor and the drive.
F_OF
Output fault:
Transistor fault
Failed output transistor.
Contact technical support.
Grounded motor phase.
Check the motor and motor cable.
F_OF1
Output fault:
Ground fault
Excessive capacitive charging
current of the motor cable.
Use shorter motor cables with a
lower charging current.
