][Funktion_Encoder_Emu_SSI
Output of SSI signals
Functions:
With this encoder emulation, positional data for the SSI interface is pre-
pared from the existing output signals from the resolver or SinCos en-
coder.
` A max. 32 Bits are transferred.
` Single-turn: The leading 12 to 16 Bits are zero, the following 16 Bits
indicate the position. On 2-pole resolvers the position value refers to
a full revolution of the motor; on 4-pole resolvers it refers to half a rev-
olution and on 6-pole resolvers to one third of a revolution.
` Multi-turn: The leading 12 to 16 Bits indicate the number of revolu-
tions; the following 16 bits state the position.
