CONFIG_ENCODER_MODE

This structure defines the encoder input mode configuration for each encoder channel. It specifies how the A/B/Z/S signals are interpreted, their polarity or counting mode, and the pulse-per-revolution configuration. This is mainly used when setting up external encoders or conveyor tracking encoders.

BYTE#	Field Name	Data Type	Value	Remarks
0	_iChannel	unsigned char	0~1	Encoder channel index
1	_iABMode	unsigned char	0~4	A/B phase mode configuration 0: A/B not used 1: A(QEP), B(QEP) 2: A(Count), B(Direction) 3: A(Up Count), B(Not Used) 4: A(Down Count), B(Not Used)
2	_iZMode	unsigned char	0~2	Z-phase signal mode 0: Not used 1: Cumulative compensation 2: Count clear
3	_iSMode	unsigned char	0	S-phase signal mode (0: Not used)
4	_iInvMode	unsigned char	0 or 1	Inversion mode (0: Forward, 1: Inversed)
8	_nPulseAZ	unsigned int	0~100000	Number of A pulses per Z pulse (counts per revolution)
