Alarm Type Description
AnalogCflct
➁
More than one of the drive's reference inputs (Pars 70 , 75 and 80 [Anlg Inx
Sel], Pars 1323 - 1327 [DPI Px Select], or Par 1021 [Encoder Out Sel]) are set
to "Speed Ref A" or "Speed Ref B". This alarm takes precedence over the
“EncoderCflct” alarm when both are present. Refer to
Figure C.1 or Speed
Reference Selection on page D-5 for a graphical representation of the drive's
reference selections.
Arm
Overvoltage
➀
There is a possible overvoltage on the armature circuit or Par 175 [Rated
Motor Volt] is set too low for the application. Refer to the “Arm Overvoltage”
fault description on
page 4-4 for more information.
Auxiliary Input
➀
An auxiliary input interlock is open or a voltage (+15 - 30 V) or reference
signal is missing for the digital input set to 14 “Aux Fault”. Refer to the
“Auxiliary Input” fault description on
page 4-4 for more information.
BipolarCflct
➁
Par 1322 [Direction Mode] is set to “Bipolar” or “Reverse Dis” and one or more
of the following digital input functions is configured: “Fwd/Reverse,” “Run
Forward,” “Run Reverse,” “Jog Forward” or “Jog Reverse.”
