Panel communication is lost and either:
• Drive is in local control mode (the control panel displays LOC), or

Motor is hot, based on either the drive's estimate or on temperature
feedback. This alarm warns that a Motor Underload fault trip may be
near. Check:
• Check for overloaded motor.
• Adjust the parameters used for the estimate (3005...3009).
• Check the temperature sensors and Group 35 parameters.
Motor load is lower than expected. This alarm warns that a Motor
Underload fault trip may be near. Check:
• Motor and drive ratings match (motor is NOT undersized for the
drive)
• Settings on parameters 3013 to 3015
Motor is operating in the stall region. This alarm warns that a Motor
Stall fault trip may be near.
This alarm warns that the drive is about to perform an automatic fault

• Any motor (when Autochange is used),
• The speed regulated motor (when Autochange is not used).
This alarm warns that the PID sleep function is active, which means
that the motor could accelerate when the PID sleep function ends.
• To control PID sleep, use parameters 4022...4026 or 4122...4126.
