(27)unsigned char i8091_LIMIT_X(unsigned char cardNo) to request the condition of X-axis limit switches

cardNo : board number 0~19.

MSB 7	6	5	4	3	2	1	0 LSB
/EMG	/FFFF	/FFEF	/LS14	xx	xx	/LS11	/ORG1

/ORG1 : original point switch of X-axis, low active.

/LS11, /LS14 : limit switches of X-axis, low active, which must be configured as Fig.(5).

/EMG : emergency switch, low active.

/FFEF : active low, FIFO is empty

/FFFF : active low, FIFO is full

Example:

unsigned char limit1; limit1 = i8091_LIMIT_X(1);

(28)unsigned char i8091_LIMIT_Y(unsigned char cardNo) to request the condition of Y-axis limit switches

cardNo : board number 0~19.

MSB 7	6	5	4	3	2	1	0 LSB
ystop	xstop	xx	/LS24	xx	xx	/LS21	/ORG2

/ORG2 : original point switch of Y-axis, low active.

/LS21, /LS24 : limit switches of Y-axis, low active, which must be configured as Fig.(6).

xstop: 1:indicate X-axis is stop

ystop: 1:indicate Y-axis is stop Example:

unsigned char limit2; limit2 = i8091_LIMIT_Y(1);

(29)i8091_WAIT_X(unsigned char cardNo) to wait X-axis going to STOP state. cardNo : board number 0~19.
