Data Fields
IfxStdIf_Pos_Dir	direction	rotation direction
float32	maxSpeed	Absolute maximal allowed speed. Above speed is recognized as error.
float32	minSpeed	Absolute minimal allowed speed. below speed is recognized as 0rad/s.
Ifx_GPT12 *	module	Pointer to the GPT12 module.
sint32	offset	raw position offset
float32	positionConst	constant for calculating mechanical position (in rad) from raw position
sint32	rawPosition	raw position in ticks. Note : the value already contains the offset
sint32	resolution	resolution of this position sensor interface
float32	speed	mechanical speed in rad/s
float32	speedConstPulseCount	constant for calculating mechanical speed (in rad/s) from raw speed in pulse count mode
float32	speedConstTimeDiff	constant for calculating mechanical speed (in rad/s) from raw speed in time diff mode
boolean	speedFilterEnabled	Enable / disable the speed low pass filter.
Ifx_LowPassPt1	speedLpf	Low pass filter object.
float32	speedModeThreshold	treshold used for speed calculation using pulse count mode or time diff mode in rad/s
sint32	speedModeThresholdTick	treshold used for speed calculation using pulse count mode or time diff mode in ticks
IfxStdIf_Pos_Status	status	error code (0 = no error)
sint32	turn	number of mechanical turns
IfxGpt12_IncrEnc_Update	update	Update call back API.
float32	updatePeriod	update period in seconds
