Function description
Parameter
ENCMODE
1 = incremental en-
coder
3 = Incremental en-
coder interpolation
Timing diagram for the incremental encoder signal:
}
a: Edge spacing ≥ 0.2 μs
}
tv: Edge steepness ≤ 0.1 μs
}
NI – td: Delay ≤ 0.1 μs
} |ΔU| ≥ 2 V/20 mA
}
Default count direction: Upwards, facing the motor axis when rotating clockwise
Output of SSI signals
Functions:
With this encoder emulation, positional data for the SSI interface is prepared from the exist-
ing output signals from the resolver or SinCos encoder.
}
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.
