The controller reacts i n different ways depending on the three possible types
of fault TRIP, message or warning:
TRIP (display of keypad XT: )
ƒ Switches the power outputs U, V, W to a high resistance until TRIP is
reset
ƒ Entry of the fault indication into the history buffer as ”current fault” in
C0168/1.
ƒ The drive is coasting without control!
ƒ After TRIP reset ( 9.5-1):
– The drive accelerates to its setpoint along the set ramps.
– The fault i ndication is moved into C0168/2 as ”last fault”.
Message (display of keypad XT: )
ƒ Tristates the power outputs U, V, W.
