Drive behaviour in the event of faults
The controller responds differently to the three possible fault types (TRIP, message, or warning):
TRIP (keypad display: $)
ƒ Switches the power outputs U, V, W to high resistance until TRIP is reset.
ƒ The fault indication is entered into C0161 of the history buffer as "current fault".
ƒ The drive coasts without control!
ƒ After TRIP reset ( 163):
– The drive accelerates to its setpoint along the set ramps.
– The fault indication is moved to C0162 as "last fault" and is deleted in C0161.
Messages (keypad display: )
ƒ Switches the power outputs U, V, W to high resistance.
ƒ Messages are not entered into the history buffer.
ƒ The drive coasts without control as long as the message is active!
ƒ If the message is no longer active, the drive starts automatically.
Warnings
"Heatsink overtemperature" (keypad:OH %)
ƒ The drive is operated in a controlled mode!
ƒ The warning signal goes off if the fault is no longer active.
"Error in motor phase" (keypad:LP1)
"PTC monitoring" (keypad:OH51)
ƒ The drive is operated in a controlled mode!
ƒ The fault indication is entered into C0161 of the history buffer as "current fault".
ƒ After TRIP reset the fault indication is moved to C0162 as "last fault" and is deleted in C0161.
