0 / uint16
(Visible when 92.1 Encoder 1 type = Absolute encoder)
Defines the number of bits used to indicate position within
one revolution. For example, a setting of 15 bits
corresponds to 32768 positions per revolution.
The value is used when parameter 92.11 Absolute position
source is set to EnDat, Hiperface or SSI. When parameter
92.11 Absolute position source is set to Tamagawa, this
parameter is internally set to 17.
Note: With an EnDat or HIPERFACE encoder and FEN-11
FPGA version VIE12200 or later, this parameter is
automatically set upon validation of encoder settings (91.10
Encoder parameter refresh).
