Coincidence signal
reset command
•Turn ON to reset the counter value coincidence (X02).
•Note that the ON/OFF time must be 2ms or longer. *1
•Turn OFF the coincidence signal reset command (Y01) when the
counter value coincidence (X02) is reset.

Preset command
•Turn ON to execute the preset function.
•Note that the ON/OFF time must be 2ms or longer. *1
•Turn OFF the preset command (Y02) when the preset value
setting (Un\G4 and 5) is stored to the present value A (Un\G10
and 11)/present value B (Un\G200 and 201).
•For general operation, refer to "Section 5.4".

Subtraction count
command
•Turn ON to perform the subtraction count at 1-phase pulse input
mode.
•If either phase B pulse is input or the subtraction count command
(Y03) turns ON, the subtraction count is performed.
•Check that the phase B pulse is input and the subtraction count
command (Y03) is OFF for addition.
•This command operates as follows when the pulse input mode is
1 multiple of 1 phase.
