Troubleshooting the Drive

12-7

Drive OL
Level 1

The calculated IGBT temperature requires a reduction in
PWM carrier frequency. If Drive OL Mode (150) is disabled
and the load is not reduced, an overload fault will
eventually occur.

Drive OL
Level 2

The calculated IGBT temperature requires a reduction in
Current Limit. If Drive OL Mode (150) is disabled and the
load is not reduced, an overload fault will eventually occur.

Flux Amps
Ref Rang

Result of autotune procedure (61).

IntDBRes
OvrHeat

The drive has temporarily disabled the dynamic braking
regulator because the resistor temperature has exceeded
a predetermined value.

IR Volts
Range

The drive autotuning 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

Motor leakage inductance is out of range.

MaxFreq
Conflict

The sum of Maximum Speed (82) and Overspeed Limit
(83) exceeds Maximum Freq (55). Raise Maximum Freq
(55) or lower Maximum Speed (82) and/or Overspeed
Limit (83) so that the sum is less than or equal to
Maximum Freq (55).

Motor
Type Cflct

Motor Type (40) has been set to Sync Prm Mag or Sync
Reluc, and one or more DC functions (for example, DC
Boost, DC Brake, etc.) have been activated. DC injection
functions are incompatible with synchronous motors and
may demagnetize them.

NP Hz
Conflict

Fan/pump mode is selected in Torq Perf Mode (53), and
the ratio of Motor NP Hertz (43) to Maximum Freq (55) is
greater than 26.

Power
Loss

Drive has sensed a power line loss.

Prechrg
Actv

Drive is in the initial DC bus precharge state.

Sleep
Config

Sleep/Wake configuration error.
When Sleep-Wake Mode [178] = Direct, possible causes
include:
- Drive is stopped and Wake Level [180] < Sleep Level
[182]
- Digital Inx Sel [361 to 366] is not set to one of the
following: Stop=CF, Run, Run Forward, or Run Reverse.
