(5) Check for abnormality in the master device (PLC, etc.)
(6) Check in voltage of 100 V AC or 200 V AC motor drive DC power supply
Check for momentary power failure, voltage drop, power failure, etc.
(7) Check in voltage of 24 V DC control power supply
Check for momentary power failure, voltage drop, power failure, etc.
(8) Confirm the generated alarm
Check the alarm information with the teaching tool.
(9) Check the connectors for disconnection or incomplete connection
(10) Check the cables for connection error, disconnection or snagging
Cut off the main power supply of the equipment (to avoid electric shock) and remove the
cables around the measurement point (to avoid conductivity through the surrounding
circuit) before checking the conductivity.
(11) Check the I/O signals
Use the master device and ELECYLINDER teaching tool to check for inconsistency or
abnormality in the input/output signal status of the two units.
(12) Check the noise elimination measures (grounding, connection of noise filter,
etc.)
(13) Check the events leading to the occurrence of the problem, as well as the
operating conditions at the time of occurrence
(14) Analyze the cause
(15) Countermeasures
Caution
When troubleshooting, exclude normally functioning parts from the targets to narrow
down the causes.
First, check (1) to (13) so that countermeasures can be taken swiftly.
