Function Description
}
A max. 32 Bits are transferred.
}
Singleturn: The leading 12 to 16 Bits are zero, the following 16 Bits indicate the posi-
tion. On 2-pole resolvers the position value refers to a full revolution of the motor; on 4-
pole resolvers it refers to half a revolution and on 6-pole resolvers to one third of a re-
volution.
}
Multiturn: The leading 12 to 16 Bits indicate the number of revolutions; the following 16
bits state the position.
