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

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.

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

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.
