Description
FB1.BISSBITS specifies the number of BiSS sensor (position) bits for the BiSS Mode C
encoder in use. Typically the value is either 26 or 32 for a BiSS Mode C Renishaw encoder. The
required value for this parameter is provided by the feedback device manufacturer for the par-
ticular device being used.

Description
This parameter sets or gets the resolution of the motor encoder (encoder feedback systems
only) in number of counts per revolution for a rotary motor and the number of encoder pitches
per motor pole pitch for a linear motor. The number of encoder counts per revolution is obtained
by multiplying the motor catalog resolution in units of PPR by four. For example, for a 1024
PPR resolution motor, the number of encoder counts per revolution is 1024*4 = 4096. For this
motor FB1.ENCRES must be set to 4096.
