300 VERIFY ERROR (SYSTEM CONFIG-DATA)
20 Machine Safety board save
data error
The safety logic circuit files in the file written in the Main
CPU circuit board (type: YCP21-E) and the machine
safety circuit board (type: YSF21-E) does not match.
Refer to section 8.23.6.2 “Machine Safety Flash Data
Erase or Reset" on page 8-271 for more details to
restore.
4776 M-SAFETY YSF LOGIC FILE SIGNAL ERR
0 Start-up, in reading information
from the FlashROM of YSF21
board, YSF21 board has
detected an undefined signal.
The error of the safety logic circuit is detected when
startup. Check the safety logic circuit because an
invalid I/O signal is used by the safety logic signal.
1 In the receiving information on
safe logic circuit information,
YSF21 board has detected an
undefined signal.
The error is detected when updating the file. Check the
safety logic circuit because an invalid I/O signal is used
by the safety logic signal.
4777 TRANSMISSION ERROR (M-SAF FILE)
1 Safe logic circuit information
transmission error was
detected.
An alarm occurred while transferring the safety logic
circuit file to the machine safety circuit board
(type:YSF21-E). Reset the alarm, and re-send the
safety logic circuit file.
2 Timer delay information
transmission error was
detected.
An alarm occurred while transferring the safety logic
circuit file to the machine safety circuit board
(type:YSF21-E). Reset the alarm, and re-send the
safety logic circuit file.
3 M-safety signal alloc information
transmission error was
detected.
An alarm occurred while transferring the safety logic
circuit file to the machine safety circuit board
(type:YSF21-E). Reset the alarm, and re-send the
safety logic circuit file.
4 Safety signal board alloc
information transmission error
was detected.
An alarm occurred while transferring the safety logic
circuit file to the machine safety circuit board
(type:YSF21-E). Reset the alarm, and re-send the
safety logic circuit file.
253 M-safety command reception
time out was detected.
No response from the machine safety circuit board
(type:YSF21-E) while transferring the safety logic
circuit file. Reset the alarm, and re-send (perform the
writing) the safety logic circuit file. If the alarm occurs
again, replace the machine safety circuit board (type:
YSF21-E).
254 Safe logic circuit write error was
detected.
Failure to transfer the safety logic circuit file to the
machine safety circuit board (type:YSF21-E). Please
re-send the safety logic circuit file. If the alarm occurs
again, refer to chapter 8.23.6.2 for more details.
255 Safe logic circuit cancel error
was detected.
Failure to sending the cancel command while
transferring the safety logic circuit file to the machine
safety circuit board (type:YSF21-E). Please re-send the
safety logic circuit file. If the alarm occurs again, refer
to chapter 8.23.6.2 for more details.
