NOTE Following an over current or overload trip (3, 4, 5, 15), the drive may not be reset until the reset time delay has elapsed to prevent
damage to the drive.

Suggested Remedy
Not required.
Check external brake resistor condition and connection wiring.
The drive has tripped to prevent damage to the brake resistor.
Instantaneous Over current on the drive output. Excess load or shock load on the motor.
NOTE Following a trip, the drive cannot be immediately reset. A delay time is inbuilt,
which allows the power components of the drive time to recover to avoid damage.
The drive has tripped after delivering >100% of value in P-08 for a period of time to
prevent damage to the motor.
Check the supply voltage is within the allowed tolerance for the drive. If the fault occurs
on deceleration or stopping, increase the deceleration time in P-04 or install a suitable
brake resistor and activate the dynamic braking function with P-34.
The incoming supply voltage is too low. This trip occurs routinely when power is removed
from the drive. If it occurs during running, check the incoming power supply voltage and
all components in the power feed line to the drive.
The drive is too hot. Check the ambient temperature around the drive is within the drive
specification. Ensure sufficient cooling air is free to circulate around the drive.
Trip occurs when ambient temperature is less than -10°C. Temperature must be raised
over -10°C in order to start the drive.
E-trip requested on digital input 3. Normally closed contact has opened for some reason.
If motor thermistor is connected check if the motor is too hot.
Check communication link between drive and external devices. Make sure each drive in
the network has its unique address.
Check incoming supply phases are all present and balanced.
Check incoming power supply phases are present and balanced.
Check for short circuits on the motor and connection cable.
NOTE Following a trip, the drive cannot be immediately reset. A delay time is inbuilt,
which allows the power components of the drive time to recover to avoid damage.
Press the stop key. If the fault persists, consult you supplier.
Check the analog input connection(s).
Press the stop key. If the fault persists, consult you supplier.
Connected motor thermistor over temperature, check wiring connections and motor.
Check / replace the cooling fan.
Indicates a fault on the output of the drive, such as one phase missing, motor phase
currents not balanced. Check the motor and connections.
The motor parameters measured through the autotune are not correct.
Check the motor cable and connections for continuity.
Check all three phases of the motor are present and balanced.
Check the incoming Modbus RTU connection cable.
Check that at least one register is being polled cyclically within the timeout limit set in
P-36 Index 3.
Check the incoming CAN connection cable.
Check that cyclic communications take place within the timeout limit set in P-36 Index 3.
