Troubleshooting and Diagnostics
Fault
Cause
Remedy
(1)
Digital Input
Configuration fault (P11...
P13)
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 (P11…
P13) or feedback source (P01).
One of the digital inputs (P11…P13) is
set to 10 and another is set to 11…14.
Reconfigure digital inputs
One of the digital inputs (P11…P13)
is set to 11 or 1 and another is set to
13 or 14.
PID enabled in Vector Torque mode (P00
= 1 or and P300 = 5)
PID cannot be used in Vector Torque mode
Remote keypad fault
Remote keypad disconnected
Check remote keypad connections
L
Low DC Bus Voltage fault
Mains voltage too low
Check mains voltage
1
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.
Module communication fault
Communication failure between drive and
Network Module.
Check module connections
Network Faults
Refer to the module documentation. for
Causes and Remedies.
Output fault:
Transistor fault
Output short circuit
Check motor/motor cable
Acceleration time too short
Increase P104, P15
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
Output fault: Ground fault
Grounded motor phase
Check motor and motor cable
Excessive capacitive charging current of
the motor cable
Use shorter motor cables with lower
charging current
Motor Overload fault
Excessive motor load for too long
• Verify proper setting of P108
•
Verify drive and motor are proper size
for application
(1) The drive can only be restarted if the error message has been reset
