Rockwell Automation 20M LPM15 Liquid-Cooled Adjustable Frequency AC Drive FRN 2.xxx - Manual (Page 89)

Troubleshooting 4-7
Dig In ConflictB 18
➁
A digital Start input has been configured without a Stop input or
other functions are in conflict. Combinations that conflict are marked
with a “ ” and will cause an alarm.
Dig In ConflictC 19
➁
More than one physical input has been configured to the same input
function. Multiple configurations are not allowed for the following
input functions:
Forward/Reverse Run Reverse Bus Regulation Mode B
Speed Select 1 Jog Forward Acc2 / Dec2
Speed Select 2 Jog Reverse Accel 2
Speed Select 3 Run Decel 2
Run Forward Stop Mode B
Drive OL Level 1 8
➀
The calculated IGBT temperature requires a reduction in PWM
frequency. If [Drive OL Mode] is disabled and the load is not
reduced, an overload fault will eventually occur.
Drive OL Level 2 9
➀
The calculated IGBT temperature requires a reduction in Current
Limit. If [Drive OL Mode] is disabled and the load is not reduced, an
overload fault will eventually occur.
FluxAmpsRef
Rang 26
➁
The calculated or measured Flux Amps value is not within the
expected range. Verify motor data and rerun motor tests.
IntDBRes
OvrHeat 6
➀
The drive has temporarily disabled the DB regulator because the
resistor temperature has exceeded a predetermined value.
IR Volts Range 25
➁
The drive auto tuning default is “Calculate” and the value calculated
for IR Drop Volts is not in the range of acceptable values. This alarm
should clear when all motor nameplate data is properly entered.
Ixo Vlt Rang 28
➁
Motor leakage inductance is out of range.
MaxFreq Conflict 23
➁
The sum of [Maximum Speed] and [Overspeed Limit] exceeds
[Maximum Freq]. Raise [Maximum Freq] or lower [Maximum Speed]
and/or [Overspeed Limit] so that the sum is less than or equal to
[Maximum Freq].
Motor Type Cflct 21
➁
[Motor Type] has been set to “Synchr Reluc” or “Synchr PM” and
one or more of the following exist:
•[Torque Perf Mode] = “Sensrls Vect,” “SV Economize” or “Fan/Pmp V/Hz.”
•[Flux Up Time] is greater than 0.0 Secs.
•[Speed Mode] is set to “Slip Comp.”
•[Autotune] = “Static Tune” or “Rotate Tune.”
NP Hz Conflict 22
➁
Fan/pump mode is selected in [Torq Perf Mode] and the ratio of
[Motor NP Hertz] to [Maximum Freq] is greater than 26.
Power Loss 3
➀
Drive has sensed a power line loss.
Precharge Active 1
➀
Drive is in the initial DC bus precharge state.
Sleep Config 29
➁
Sleep/Wake configuration error. With [Sleep-Wake Mode] = “Direct,”
possible causes include: drive is stopped and [Wake Level] < [Sleep
Level].“Stop = CF,” “Run,” “Run Forward,” or “Run Reverse” is not
configured in [Digital Inx Sel].
Speed Ref Cflct 27
➁
[Speed Ref x Sel] or [PI Reference Sel] is set to “Reserved”.
Start At PowerUp 4
➀
[Start At PowerUp] is enabled. Drive may start at any time within 10
seconds of drive powerup.
UnderVoltage 2
➀
The bus voltage has dropped below a predetermined value.
