CHAPTER 8 TROUBLESHOOTING
8.1 Initial Checks
About Errors That
Occur During
Motor Calibration
8–2
If trouble occurs, first of all check the following:
(1) Power supply
Make sure that the power supply is ON. Also, make sure that the pow
er supply is within the rated voltage range.
(2) Input type jumper
Make sure that the input type jumper is set to the correct input type.
The table below describes the operations when the jumper is not set
matched to the type of sensor connected to the input terminal.

Current (4 to 20 mA)
(3) Wiring
Make sure that all cables are properly connected.
(4) Communications conditions
When communicating via the RS 232C, RS 422 or RS 485 interfaces,
make sure that the baud rate and other communications condition
settings on the host computer and E5AK T controller are matching,
and are within the permissible ranges.
If there appears to be nothing wrong after checking the E5CK T controller,
and the same phenomenon continues, check the controller in more detail,
for example, on the error display.
If an error occurs during motor calibration, 
The following causes of errors are possible:
• Control motor or potentiometer malfunction
• Incorrect control motor or potentiometer wiring
• Potentiometer is not connected
