Description
Possible Causes
Motor wiring or connection error.
„
Loss of motor connection with the drive or broken wire.
„
Overload on the motor shaft.
„
Load cycle is too high (high number of starts and
„
stops per minute).
High ambient temperature around the motor.
„
Poor contact or short circuit (3.9 kΩ < R
„
Motor thermistor not installed.
„
Motor shaft is stuck.
„
Electric noise.
„
Inverter firmware fault.
„
Poor contact in the connection between the main
„
control and the power pack.
Hardware not compatible with the firmware version.
„
Defect on the internal circuits of the inverter.
„
Wiring on DI1 to DI8 inputs are open or have poor
„
contact.
Hardware identification fault; compare P0295 and
„
P0296 to the inverter identification label.
Inverter internal circuits fault.
„
Check network installation, broken cable or fault/
„
poor contact on the connections with the network,
grounding.
Ensure the master always sends telegrams to the
„
equipment in a time shorter than the setting in P0314.
Disable this function in P0314.
„
Check if the communication interface with the HMI is
„
properly configured in parameter P0312.
HMI cable disconnected.
„
Fault in the HVAC plug-in connection.
„
Fault in the communication between the HVAC plug-in
„
board and the main control board.
Fault in the SoftPLC boot by the CPU.
„
Parameter P1030 is programmed for 2 and the value
„
of the process variation of the main PID controller
remained below the value programmed in P1031 for
the time programmed in P1032.
Parameter P1030 is programmed for 2 and the value
„
of the process variation of the main PID controller
remained above the value programmed in P1033 for
the time programmed in P1034.
Parameter P1042 is programmed for 2 and the pump
„
driven by the CFW501 frequency inverter is running
with speed above the speed programmed in P1043
and the motor torque remained below the value
programmed in P1044 for the time programmed
in P1045.
