Possible Causes
Check the wiring and the ground installation.
Make sure that the inverter has sent a new message
within the time interval set at P0314.
Broken or disconnected cable.
The power supply is turned off.
Incorrect communication baud rate.
Two network slaves with the same address.
Wrong cable connection (inverted signals).
Communication problems.
Wrong master configuration/settings.
Incorrect configuration of the communication objects.
PLC in IDLE mode.
PLC command register bit set to zero (0).
One or more allocated I/O connections have entered
the timeout state.
Verify the network master status, making sure it is in
the execution mode (Run).
Refer to the Profibus DP communication manual for
more information.
Verify whether the network master is correctly
configured and operating normally.
Verify the network installation in a general manner -
cable routing, grounding.
Refer to the Profibus DP communication manual for
more information.
Verify whether the Profibus DP module is correctly
fit into the slot 3.
Refer to the Profibus DP communication manual for
more information.
Wrong settings of P0161 and/or P0162.
Problem with a hoist-type load.
Defective FLASH memory module.
Check the connection of the FLASH memory module.
High surrounding air temperature (>50 °C (122 °F)) and
high output current.
Defective internal fan (if existent).
High temperature (> 45 ºC) inside the cabinet.
High surrounding air temperature (>50 °C (122 °F)) and
high output current.
Defective internal fan (if existent).
Surrounding air temperature ≤ -30 °C (-22 °F).
