11.6 Data Protection
11.6.1 Duplicate Data
The data related to the safety function is copied to the safety circuit
board’s memory or PFL circuit board’s memory for safety.
When the control power is turned ON, check is performed to see that
duplicate data are set the same. If they are different when the control
power is turned ON, the following alarm occurs.
When there is difference in the Safety Circuit Board:
Alarm 0300: “VERIFY ERROR (SYSTEM CONFIG-DATA) [10]”
When there is difference in the PFL Circuit Board:
Alarm 0300: “VERIFY ERROR (SYSTEM CONFIG-DATA) [13]”
In the system with the functional safety function, a message “Select
‘Safety Board FLASH Reset’ in the maintenance mode” is displayed after
the following operations.
Turning ON or OFF causes error without FLASH Data Reset.
• The data related to the safety function is loaded from an external
storage in Software Pendant.
• A parameter related to the safety function is rewrote by setting
operations in maintenance mode.
• The zeroing function is performed.
• Encoder is reset
In case one of the above-mentioned operations is performed, FLASH
Data Reset is required.
In the maintenance mode, there are cases when parameters related to the
safety function are rewritten by several setting operations.
For this reason, the message “Select ‘Safety Board FLASH Reset’” may
be displayed. Perform the safety board FLASH reset operation in this
case.
11.6.2 Safety Board FLASH Reset
If the following alarm occurs when the control power supply is turned ON,
Alarm 0300: “VERIFY ERROR (SYSTEM CONFIG-DATA) [10]”
Alarm 0300: “VERIFY ERROR (SYSTEM CONFIG-DATA) [13]”
perform the Safety Board FLASH RESET to reset the data of the safety
circuit board and PFL circuit board. To perform FLASH Data Reset, refer
to chapter 12.4.3.3 “Safety Board Flash Reset”.
When FLASH Data reset is required, Smart Pendant cannot
operate the YRC Controller. Use Software Pendant and
perform Safety Board FLASH Reset.
For detail on the Software Pendant, refer to chapter 12
“Software Pendant”.
