FS26 Safety Outputs release

dingyazhou — Mon, 15 Nov 2021 07:06:46 GMT

Hello, I want to ask whether the fail-safe output release function Sbc_fs26_FsxbRelease of the FS26 chip needs to be called in a loop

Hello Yazhou,

There is no need to call this function in a loop to release FSxB.

The below diagram provides high level flow chart to enter Normal mode in the application.

Best regards,

Tomas

Hello, I have another question, is our error flag register, such as FS_OVUV_REG_STATUS register is cleared after error clearance, or do you need to manually write "1" software?

Hello Yazhou,

It is necessary to write a 1 in order to clear the error flags bits. This is typically denoted in the FS26xx datasheet as “Clear on write to 1.”

Best regards,
