• General
The detection accuracy is based on the fixed-cycle processing of the Motion CPU. General detection accuracy is used even
when the input module setting is "Enable synchronization between modules".
• High-accuracy
When the input module setting is "inter-module synchronization valid", by setting the high-speed input request signal
accuracy to "High-accuracy", high-speed input request signals can be controlled with high accuracy. If this signal is
specified for a signal that is not compatible with high-accuracy input, a moderate error (error code: 30D3H) occurs.
For sensing module input, the high-speed input request signal accuracy is set in the servo parameters. Refer
to the following for details of servo parameters.
Sensing Module Instruction Manual
• When the high-speed input request signal accuracy of the sensing module is set to general, set "0: Digital
input" in the servo parameter "DI setting 2 (function selection)".
• When setting the high-speed input request signal accuracy of the sensing module to high-accuracy, set "1:
Timing-latch input" in the servo parameter "DI setting 2 (function selection)". By setting a sensing module
DI signal that supports the timing-latch input function, control accuracy using the high-speed input request
signal can be changed to high-accuracy. Refer to timing-latch input function for details of timing-latch input
function. (Page 240 Timing-latch input function)
