Troubleshooting
Drive Powerup
49
No fault displayed. Used as a Power Up Marker in the Fault Queue
indicating that the drive power has been cycled.
Enable Hardware 111
Safe-Off board is not installed
and pins 3 and 4 of the Safe-Off
Connector are not jumpered.
Install Safe-Off board or jumper pins
3 and 4.
Safe-Off board has failed.
Replace Safe-Off board.
Hardware enable circuitry failed. Replace control board.
Encoder Loss
91
One or both encoder channel
signals is missing.
1. Check Wiring.
2. Replace encoder.
Excessive Load
79
Motor did not come up to speed
in the allotted time during
autotune.
1. Uncouple load from motor.
2. Repeat Autotune.
Faults Cleared
52
No fault displayed. Used as a marker in the Fault Queue indicating that
the fault clear function was performed.
Flt QueueCleared 51
No fault displayed. Used as a marker in the Fault Queue indicating that
the clear queue function was performed.
FluxAmpsRef
Rang
78
The value for flux amps
determined by the Autotune
procedure exceeds the
programmed [Motor NP FLA].
1. Reprogram [Motor NP FLA] with
the correct motor nameplate
value.
2. Repeat Autotune.
Heatsink
OvrTemp
8
➀
Heatsink temperature exceeds
100% of [Drive Temp].
1. Verify that maximum ambient
temperature has not been
exceeded.
2. Check fan.
3. Check for excess load.
HW OverCurrent
12
➀
The drive output current has
exceeded the hardware current
limit.
Check programming. Check for
excess load, improper DC boost
setting, DC brake volts set too high
or other causes of excess current.
Incompat
MCB-PB
106
➁
Drive rating information stored on
the power board is incompatible
with the main control board.
Load compatible version files into
drive.
Input Phase Loss 17
The DC bus ripple has exceeded
a preset level.
Check incoming power for a missing
phase/blown fuse.
IR Volts Range
77
“Calculate” is the autotune
default and the value determined
by the autotune procedure for IR
Drop Volts is not in the range of
acceptable values.
Re-enter motor nameplate data.
IXo VoltageRange 87
Voltage calculated for motor
inductive impedance exceeds
25% of [Motor NP Volts].
1. Check for proper motor sizing.
2. Check for correct programming of
[Motor NP Volts], parameter 41.
3. Additional output impedance may
be required.
Load Loss
15
Drive output torque current is
below [Load Loss Level] for a
time period greater than [Load
Loss time].
1. Verify connections between
motor and load.
2. Verify level and time
requirements.
Fault
No.
