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
VoltageRange
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
[Fault Config 1] or [Alarm Config 1] Bit 7 “Motor Therm” is enabled and the
analog Input voltage is <0.2 Volts or >5.0 Volts.
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
[Fault Config 1] or [Alarm Config 1] Bit 7 “Motor Therm” is enabled and
Analog In 1 is set to milliamperes.
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”.

PowerUp
4
➀
[Start At PowerUp] is enabled. Drive may start at any time within 10 seconds
of drive powerup.
