It shows the type of time-out (minimum interval time between two
transmission sequences) set in the encoder. “04” = time-out is self-adaptable to
the clock frequency. It is
1.5
*
1 / clock frequency.
Time-out Bit 7 ... bit 3 Bit 2 Bit 1 Bit 0
Self-adaptable 0 … 0 1 0 0
If clock frequency = 50 kHz, then the time-out is 30 µs.
If clock frequency = 200 kHz, then the time-out is 7.5 µs.
If clock frequency = 10 MHz, then the time-out is 150 nsec.
Software release
[7D, ro]
It shows the software release version expressed in decimal value.
