Troubleshooting
4-11
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.
Ground Warn 15
➀
Ground current has exceeded the level set in [Gnd Warn Level].
Home Not Set 34
➀
Configurable alarm set in parameter 259, bit 17. When set to “1,” this alarm is
displayed when any of the following occur:
•
parameter 88 is set to “7” (Pos/Spd Prof)
•
on power up and parameter 88 = “7”
•
recall user sets and parameter 88 = “7”
Alarm is cleared when:
•
setting parameter 88 to a value other than “7”
•
reset defaults
•
parameter 259, bit 17 is cleared
•
a digital input is configured as “Set Home” and input is True
•
parameter 705, bit 9 is “Enabled”
•
parameter 700, bit 13 (At Home) is “Enabled” - position regulator will set
this bit if device is “home”
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.
PI Config
Conflict
52
➁
Check [PI Configuration], both “AdjVoltTrim” & “Torque Trim” are selected.
Alarm
No
