14.2.4.1. Memory Error
[Output]
DRDY: Open
[TA]
E0 > Memory Error
[LED]
E0
[Motion Condition]
Servo-OFF
Table 14-10: Cause and Remedy: Memory error
Cause
Remedy
(1) Parameters stored in the memory have
been rewritten by noise or other cause.
·
Initialize the memory then reenter the parameters.
(Refer to “12. Command and Parameter”.)
(2) Faulty PCB.
(When the memory is not functioning
after initialized.)
·
Replace Driver Unit.
(Refer to “Appendix 4. How to Replace ESA13 Driver
Unit”.)
à
Command “SI” initializes the memory. After initializing, some parameters are reset to
shipping set. Resetting parameters are necessary.
à
When the memory error occurs, read out of a parameter with “TA” command will be
all “0” (Zero).
