6.6.5.3 Object 0x561F: Bit rate
The <BitRate> (0x561F) is used to change the clock frequency for the transmission of the bits to the valve. It
depends, i.e. on the length of the cable, the noise environment and the specification of the transducer.
Value description
6.6.5.4 Object 0x3252: SSI Error Count
The <SSIErrorCount> (0x3252) is used to delay the SSI Error for n SSI transmission cycles.
Default: after 3 incorrect SSI transmission cycles, the SSI Error (fault reaction 44) will be thrown.
6.7 Digital inputs
The servo valve has one digital input.
