R
A current path to earth ground has been detected at one or more of the
drive output terminals. Check the motor and external wiring to the drive
output terminals for a grounded condition.
U VW Output Short
Freq
P
R
A short circuit has been detected between two or more of the drive output
terminals. Check the motor and external wiring to the drive output
terminals for a shorted condition.
V UW Output Short
Freq
P
R
A short circuit has been detected between two or more of the drive output
terminals. Check the motor and external wiring to the drive output
terminals for a shorted condition.

R
A short circuit has been detected between two or more of the drive output
terminals. Check the motor and external wiring to the drive output
terminals for a shorted condition.
Negative Phase Transistor Short
Freq
P
R
A shorted drive transistor has been detected. Check drive output transistors,
both upper and lower portions of each transistor, for a shorted condition.
