9.3 Drive behaviour in the event of faults
The controller responds differently to the three possible fault types TRIP,
message, or warning:
TRIP (display in keypad XT: c A)
ƒ Switches the power outputs U, V, W to a high−resistance state until
TRIP reset is executed.
ƒ The fault indication is entered into the history buffer as "current fault"
in C0168/1.
ƒ The drive coasts without any control!
ƒ After TRIP reset (
¶ 9.5−5):
– The drive travels along the ramps to its setpoint.
– The fault indication is moved to C0168/2 as "last fault".
