2.2. List of Warning Messages
This message will appear when motor thermal model is increasing the estimated motor
temperature.
Motor current is higher than the rated current value.
This message will appear if the output current is higher than 125% of the nominal current.
Current limit algorithm has been activated.
Torque limit algorithm has been activated.
A high DC Link voltage level has been detected and the voltage limit control algorithm has
been activated to protect the drive.
Asymmetry in output currents of the drive has been detected.
Asymmetry in output voltage of the drive has been detected.
Asymmetry in input voltage of the drive has been detected.
Input voltage of the equipment is reaching a dangerous level. The value is above the set
value (protections settings).
Input voltage of the equipment is reaching a dangerous level. The value is below the set
value (protections settings).
Motor speed has reached speed limit 1.
Motor speed has reached speed limit 2.
Input current has reached the 100% of the rated current.
Inverse input current has reached the 75% of the fault threshold “R19 I IM BIN”.
Ground fault current has reached the 75% of the ground fault threshold.”R20 GRND INPUT”.
Temperature rectifier
bridge
The rectifier‟s IGBTs have reached 90ºC.
Some CAN frames from the fiber optics communication have been lost.
The rectifier‟s fan power supply has a failure. The fault “R34 IGBT TEMP” will reduce its
threshold value from 110ºC up to 90ºC, in order to protect the drive components.
