No faults, power stage Enabled
Control power not applied or
insufficient control power applied
No faults, power stage Disabled
Not Assigned
Motor Over Temp
Motor temperature exceeds allowed
limit
Drive Over/Under Temp
Temperature of drive heatsink/
chassis is outside of allowed limits
Drive I*t Too High
The product of the drives output
current multiplied by time has
exceeded allowed limits.
If current foldback is enabled, the
drive peak output current automat-
ically reduces to 0.67% of DIpeak.
If foldback is not enabled, the drive
will fault.
Motor I*I*t Too High
Motor current amplitude squared
multiplied by time has exceed al-
lowed limits
Optional Battery low
Optional fault used to indicate SFD
battery supply voltage is low
Normal opertion.
Loose or open circuit wiring of control power input.
Low input voltage to control power supply.
Hardware or Software Enable inactive. To enable drive,
apply hardware enable and set software enable.
High ambient temperature at motor.
Insufficient motor heat sinking from motor mounting.
Operating above the motor's continuous current rating.
Motor temperature sensor failure or not connected.
High or low drive ambient temperature.
Restriction of cooling air due to insufficient space
around unit.
Operating above the drive's continuous current rating.
Mechanically-jammed motor.
Motion profile acceleration requires peak current for too
long of a time duration.
Machine load on the motor increased by friction.
Wiring problem between drive and motor yielding
improper motion.
Motor commutation error.
Drive under-sized for application, friction, or load.
Mechanically-jammed motor.
Motion profile acceleration requires peak current for too
long of a time duration.
Machine load on the motor increased by friction.
Motor commutation error.
Motor under-sized for application, friction, or load.
Battery low fault enabled and battery is not installed.
SFD Battery back-up voltage is low.
