Explanation Content in This Manual
This manual explains the programming methods and data used for control of the following modules and PID control using
structured programming technique.
• Precautions on using instructions
For details of the specifications, functions, and operating timing of each instruction, refer to the related
manuals of each module.
Function/module for explaining an
instruction
Processing performed by the instruction
Reference
Analog module
• Switches the mode. (Offset/gain setting mode or normal mode)
• Reads the user range setting offset/gain value.
• Restores the user range setting offset/gain value.
Positioning module
• Restores the absolute position of the specified axis.
• Starts positioning of the specified axis.
• Executes teaching of the specified axis.
• Writes parameters/positioning data and block start data to a flash ROM.
• Initializes setting data.

I/O FUNCTION
INSTRUCTION
Counter function
• Updates the current value of the specified CH.
• Sets a ring counter lower limit value and a ring counter upper limit value.
• Sets a preset value/latch counter value/sampling counter value.
• Sets the coincidence output No. n point.
• Measures the frequency/rotation speed.
• Stores the measured pulse value.
• Outputs the PWM wave form.
Data logging function
• Generates a trigger on the data logging of the specified data logging configuration
number.
• Resets the LOGTRG instruction of the specified data logging configuration
number.
