(1) Description
AdjVoltRef Cflct 33 1 Invalid adjustable voltage reference selection conflict.
Analog In Loss 5 1 An analog input is configured for “Alarm” on signal loss and signal loss has occurred.
Bipolar Conflict 20 2 Parameter 190 [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.”
Brake Slipped 32 2 Encoder movement has exceeded the level in [BrkSlipCount] after the brake was set.
Brake Slipping 16 2 Brake slip procedure is in progress.
Decel Inhibt 10 1 Drive is being inhibited from decelerating.
Dig In ConflictA 17 2 Digital input functions are in conflict. Combinations marked with a “ ” will cause an
alarm.
Dig In ConflictB 18 2 A digital Start input has been configured without a Stop input or other functions are in
conflict. Combinations that conflict are marked with a “ ” and will cause an alarm.
Dig In ConflictC 19 2 More than one physical input has been configured to the same input function. Multiple
configurations are not allowed for the following input functions.

DPI Port1 Loss 38 1 The HIM connected to DPI Port 1-3 stopped communicating to the drive. Check the HIM
connection.
DPI Port2 Loss 39 1
DPI Port3 Loss 40 1
Drive OL Level 1 8 1 The calculated IGBT temperature requires a reduction in PWM frequency. If [Drive OL Mode]
is disabled and the load is not reduced, an overload fault will eventually occur.
Drive OL Level 2 9 1 The calculated IGBT temperature requires a reduction in Current Limit. If [Drive OL Mode] is
disabled and the load is not reduced, an overload fault will eventually occur.
FluxAmpsRef
Rang 26 2 The calculated or measured Flux Amps value is not within the expected range. Verify motor
data and rerun motor tests.
Ground Warn 15 1 Ground current has exceeded the level set in [Gnd Warn Level].
