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.
The drive has tripped after delivering >100% of value in P-08* for a period of time
to prevent damage to the motor.
Check for short circuits on the motor and connection cable
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.
Increase the panel ventilation if required. Ensure sufficient cooling air can enter the
drive, and that the bottom entry and top exit vents are not blocked or obstructed.
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
Check the analog input connection(s)
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
Drive ambient temperature too high, check adequate cooling air is provided
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
