Serial communication/optional fieldbus reset signal.

After a manual reset pressing Stop/Reset button, press Start button to restart the motor.
A warning precedes a fault.
A trip lock is an action when an fault occurs, which can damage the drive or connected equipment. Power is removed from the motor.
A trip lock can only be reset after a power cycle has cleared the condition. Once the problem has been rectified, only the fault continues
flashing until the drive is reset.
The fault words, warning words, and extended status words can be accessed via fieldbus or optional fieldbus for diagnosis.

NOTICE
Trip Cause
lock
– Signal on terminal 33 or 34 is less than 50% of the value set in
P 9.5.2.3 T33 Low Voltage, P 9.5.2.5 T33 Low Current, P 9.5.3.3
T34 Low Voltage, and P 9.5.3.5 T34 Low Current.
– No motor has been connected to the output of the drive.
X Missing phase on the supply side, or the voltage imbalance is
too high. Check the supply voltage.
– DC-link voltage exceeds the limit.
– DC-link voltage drops below the voltage warning low limit.
– More than 100% load for too long.
– Motor is too hot due to more than 100% load for too long.
– Thermistor or thermistor connection is disconnected, or the
motor is too hot.
– Torque exceeds the value set in either P 5.10.1 Motor Torque
Limit or P 5.10.2 Regenerative Torque Limit.
X Inverter peak current limit is exceeded. If this fault occurs on
power-up, check whether power cables are mistakenly con-
nected to the motor terminals.
X Discharge from output phases to ground.
X Short circuit in motor or on motor terminals.
– No communication to the drive.
– May be caused by a blocked motor.
X Brake resistor is short-circuited, thus the brake function is dis-
connected.
