The bit marked slash may be set 0 or 1.
The details of each bit are shown below. The bit is set to the underlined side at POWER ON/RESET.
(1) COUNT CLOCK TYPE (D ) ０
Selects an operation clock of the PULSE COUNTER.
0: Operated by DRIVE PULSE (XCWP, XCCWP) of the X axis MCC05v2.
1: Operated by external clocks from XEA (X axis encoder A phase signal) and XEB (X axis encoder
B phase signal).
(2) COUNT PATTERN TYPE (D , D ) １ ２
These bits become effective only when D BIT＝1, selecting an external input clock count method. ０
D D Count pattern Input clock type ２ １
0 0 Count by multiplying the XEA and XEB inputs by 1. 90ﾟ phase
0 1 Count by multiplying the XEA and XEB inputs by 2. difference clock
1 0 Count by multiplying the XEA and XEB inputs by 4.
1 1 Count-up by XEA and count-down by XEB. Independent clock
for each direction
(3) AUTO CLEAR ENABLE (D ) ３
Sets the AUTO CLEAR function.
0: No AUTO CLEAR is executed. 1: AUTO CLEAR is executed.
(4) RELOAD ENABLE (D ) ４
Sets the RELOAD function.
0: No RELOAD is executed. 1: RELOAD is executed.
(5) COMP1 INT ENABLE (D )
５
Determines whether or not to output the match output XCNTINT of COMPARE REGISTER1.
0: XCNTINT is not output. 1: XCNTINT is output.
(6) COMP1 STOP TYPE (D ) ６
Determines whether or not to put the pulse output into stop by the match output of COMPARE REGISTER1.
0: Not put into stop. 1: Put into stop.
