Meaning
While writing data to the flash memory, a
failure occurred during one of the following
operation.
• While saving a JOG speed table by using
a JSPDSTORE command
• While saving a JOG speed table by using
FnB05
• While initializing a JOG speed table by
using a JSPDINIT command
• While initializing a JOG speed table by
using FnB08
There was a request to start program table
operation even though an E19A or E1BA
alarm occurred when the control power
supply was turned ON.
There was a request to start JOG speed
table operation even though an E1FA or
E22A alarm occurred when the control
power supply was turned ON.
There was an overflow in the reception buf-
fer used for serial commands.
• An error will occur if too many serial com-
mands are sent consecutively without
waiting for the responses.
(Normally, the reception buffer will not
overflow if there is command/response
handshaking.)
• When an overflow has occurred, error
code E47E will be returned and all of the
data that has accumulated in the recep-
tion buffer will be discarded.
A parity check error occurred with the serial
command.
• This error will occur if even parity is not
being used.
• The command that caused this error will
be discarded and no response will be
returned.
• There will be no response, but the
/WARN output and LED indicators will
indicate that an error has occurred.
