14.2.4.11. RS-232C Error
u
When parameter is SE “0,”
[Output] DRDY: Close
[TA] C2 > RS232C Error
[LED] C2
[Motor Condition] Normal
u
When parameter is SE “1,”
[Output] DRDY: Open
[TA] C2 > RS232C Error
[LED] C2
[Motor Condition] Servo lock
Table 14-20: Cause anr Remedy: RS-232C error
Cause Remedy
(1) Connect or disconnect the
communication cable with power on.
·
Connect or disconnect the communication cable when
the power is off.
(2) Attempted to transmit large volume of
data without the flow control by CTS and
RTS command.
·
Wire CTS and RTS signal and apply the flow control.
(3) Wrong Baud rate is set to the terminal. · Set Baud rate to 9 600 bps.
(4) Fault
·
Replace Driver Unit.
(Refer to “Appendix 4. How to Replace ESA13 Driver
Unit.”)
Note : (1) Parameter SE can set DRDY output and condition of Motor servo when RS-232C
communication is abnormal. Refer to “12. Command and Parameter.”
(2) RS-232C error may be cleared by input of CRL or CL command.
14.2.4.12. CPU Error
[Output] DRDY: Open
[TA] C3 > CPU Error
[LED] C3
[Motor Condition] Servo-OFF
Table 14-21: Cause and Remedy: CPU error
Cause Remedy
(1) A wrong program is called due to noise.
·
Apply the remedy for noise.
(2) Memory is fault.
(3) CPU is faulty. ·
Change Driver Unit.
·
Replace Driver Unit.
(Refer to “Appendix 4. How to Replace ESA13
Driver Unit.”)
