13-6 SP600 AC Drive User Manual
DigIn Bad
Value Unsupported function selected in Digital In”x” Sel
parameters (361-366).
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.
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 (90) 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.
Speed Ref
Cflct Speed Ref A Sel (90) or PI Reference Sel (126) is set to
Reserved.
Under-
Voltage The bus voltage has dropped below a predetermined value.
