FB#.SSIBAUD
Description
FB#.SSIBAUD sets the baud rate at which to run the SSI encoder and is only used and updated when FB#.SELECT = 36 (SSI). FB#.SSIBAUD is ignored for other values of FB#.SELECT. It is recommended to leave this value set to its default unless issues arise when connecting to an SSI feedback that cannot be resolved through changing FB#.SSITYPE. It is also recommended to set this parameter before setting FB#.SELECT to 36.
As the number of single-turn and multi-turn bits increases for an SSI encoder, the baud rate may need to be increased in order to transmit all bits of data in the time required by the drive. Due to rounding, the drive will set the actual baud rate used as close to the desired baud rate written to this command. Reading FB#.SSIBAUD after a write will return the actual baud rate that was set by the drive, which may differ from the exact value written.
Example
-->FB3.SELECT 1 -->FB3.SSIBAUD 757575 [Hz] -->FB3.SSIBAUD 900000 -->FB3.SSIBAUD 900000 [Hz] -->FB3.SELECT 36 -->FB3.SSIBAUD 925925 [Hz]
