User safety sequence 2 error

Details
An error has occurred in User safety sequence 2. The screen displays the error cause.
Safety observation target axes are stopped.
User safety sequences 1 and 2 are both stopped.
All the DOs of the connected safety I/O unit are turned OFF.

Output sig. cross check error

Details
The signals output to the safety I/O unit are unmatched between PLC1 and PLC2. The screen shows the unit
No., RIO system and signal bit in error.
[M8]
bit24-27: Unit No.
bit16-17: Detected system
bit0-15: Signal BIT
[C80]
bit0-31: Signal BIT
The axes covered by safety function come to a standstill.
Remedy
Check the user safety sequence to make sure the output signal control circuit is correct.
Set tolerable time more than 300ms, when an output signal is controlled with 100ms timer.
NC unit may be faulty. Replace the NC unit.
V04 Safety observation & Smart both ON
Details
The system has both an axis for which Safety observation is enabled (the parameter "#2313 SV113(SSF8)/
bitF" or "#13229 SP229(SFNC9)/bitF" is ON) and an axis for which Smart safety observaiton is enabled (the
parameter "#51101 SF_Disable" or "#51301 SF_SDisable" is OFF).
Remedy
Disable Safety observation for all the axes (Set the parameters "#2313 SV113(SSF8)/bitF" and "#13229
SP229(SFNC9)/bitF" to OFF), and turn ON the NC reset signal.
Disable Smart safety observation for all the axes (Set the parameters "#51101 SF_Disable" and "#51301
SF_SDisable" to OFF), and turn the power OFF and ON.

Safety IO device unconnectable

Details
A safety I/O unit has been connected with the smart safety observation option OFF or with the parameters
"#51101 SF_Disable" and "#51301 SF_SDisable" set to ON for all the axes.The screen displays the channel
to which the safety I/O unit is connected by the bit number.
bit0: Operation panel
bit1: RIO 1CH
bit2: RIO 2CH
bit3: RIO 3CH
Remedy
Disconnect the safety I/O unit, and then turn OFF and ON the power.
If you wish to use Smart safety observation, implement the following and then turn the power OFF and ON.
- Enable the option.
- Turn OFF the axis parameter of Smart safety observation ("#51101 SF_Disable" / "#51301 SF_SDisable").
