• Output
The following functions occupy outputs of the high-speed input/output function. The following functions cannot be combined
with other high-speed input/output functions.
*1 When positioning is not used, the output devices (Y) for which the positioning setting is enabled with parameters can be used as PWM
outputs or general-purpose devices having no parameter.
Precautions
Do not specify an output device (Y) used by the high-speed input/output function as the output destination of the high-speed
comparison table.
■High-speed pulse input/output module
• Input
The following functions occupy inputs of the high-speed input/output function. The channels and the axis numbers are in
module internal order.
*1 The number in  is the head input number for each high-speed pulse input/output module.
*2 Simultaneous use with a function other than the high-speed counter (A phase/B phase input) is possible. However, using with the
channel 2 external enable input of the high-speed counter is not possible. However, the input logic of other functions is applied.
• Output
The following functions occupy outputs of the high-speed input/output function. The channels and the axis numbers are in
module internal order. The following functions cannot be combined with other high-speed input/output functions.
*1 The number in  is the head output number for each high-speed pulse input/output module.
Precautions
Do not specify an output device (Y) used by the high-speed input/output function as the output destination of the high-speed
comparison table.
