IK220ConfigEn
Reads the configuration of the connected EnDat encoder. The
exact meaning of the individual value is described in the EnDat
Description. With the IK220ReadMemEn function, the param-
eters of the encoder manufacturer can be read out in order to
receive further information on the encoder. This function must
be called before further EnDat functions can be used!
Prototype: BOOL
IK220ConfigEn (USHORT Axis,
USHORT* pStatus, USHORT* pType,
ULONG* pPeriod, ULONG* pStep,
USHORT* pTurns, USHORT* pRefDist,
USHORT* pCntDir);
Axis: Number of the axis (0 to 15)
pStatus: Pointer to a variable in which the EnDat status is
saved.
