ert
CAN communications failure
Phenomena Communications error occurred in CAN bus communications.
Possible Causes Check and Measures
(1) Baud rate settings differ. Check the data of baud rate (y24) and setting details of host equipment
side.
 Correct any settings that differ.
(2) Defect of host controllers
(including programmable
controller, personal computer,
etc.) (Defects of control
software, setting and hardware)
Check the host equipment.
 Remove the cause of the equipment error.
(3) Break and contact failure of
communications cables
Check the continuity of the cables, contacts and connections.
 Replace the cable.
(4) The inverter was affected by
strong electrical noise.
Check if appropriate noise control measures have been implemented
(e.g., correct grounding and routing of communications cables and main
circuit wires).
 Implement noise control measures.
 Implement noise reduction measures on the host side.

fus
DC fuse-blowing
Phenomena The fuse inside the inverter blew.
Possible Causes Check and Measures
(1) The fuse blew due to
short-circuiting inside the
inverter.
Check whether there has been any excess surge or noise coming from
outside.
 Take measures against surges and noise.
