Troubleshooting 4-11
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.
Ground Warn 15
➀
Ground current has exceeded the level set in [Gnd Warn Level].
In Phase
Loss
13
➀
The DC bus ripple has exceeded the level in [Phase Loss Level].
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.
Load Loss 14 Output torque current is below [Load Loss Level] for a time period greater
than [Load Loss time].
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
Thermistor
12 The value at the thermistor terminals has been exceeded.
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.
PTC Conflict 31
➁
PTC is enabled for Analog In 1, which is configured as a 0-20 mA current
source in [Anlg In Config].
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.
Alarm
No.
