3.1 Control Functions
Details
This function returns the setting data stored in the buffer memory/internal memory and flash ROM/internal
memory (nonvolatile) of Simple Motion module to the default values.
The following two methods can be used.
• Method using a program
• Method using an engineering tool
This function writes the execution data being used in the control into the flash ROM/internal memory
(nonvolatile).
The following two methods can be used.
• Method using a program
• Method using an engineering tool
[RD77MS]
This function sets the input type, input terminal, signal logic and input filter for each external input signal of
each axis (upper/lower stroke limit signal (FLS/RLS), proximity dog signal (DOG), and stop signal
(STOP)).
The function enables the assignment of external input signal of each axis to any terminals of the external
input connection connector on the Simple Motion module.
[RD77GF]
This function sets the input type and signal logic for each external input signal of each axis (upper/lower
stroke limit signal (FLS/RLS), proximity dog signal (DOG), and stop signal (STOP)).
This function assigns link devices to external signals of the Simple Motion module.
This function monitors start history and current value history of all axes.
This function executes the positioning control of Simple Motion module without connecting to the servo
amplifiers.
It is used to debug the program at the start-up of the device or simulate the positioning operation.
This function executes the operation as the axis (virtual servo amplifier axis) that operates only command
(instruction) virtually without servo amplifiers.
This function uses the "Master-slave operation function" of servo amplifier. The Simple Motion module
controls the master axis and the slave axis is controlled by data communication between servo amplifiers
(driver communication) without Simple Motion module.
This function is used to latch any data at the input timing of the mark detection signal (DI).
This function is used to store the data selected by user up to 4 data per axis to buffer memory and monitor
them.
This function collects errors and event information occurred in the Simple Motion module in the CPU
module, and saves them to an SD memory card.
The error history can be checked even after the power OFF or reset by holding the error contents in the
CPU module.
Temporarily connect/disconnect of SSCNET communication is executed during system's power supply
ON. This function is used to exchange the servo amplifiers or SSCNET cables.
This function reads and writes objects of slave devices with cyclic transmission.
This function reads and writes objects of slave devices with transient transmission.
Allows to replace a module without stopping the system. For procedures for the online module change,
refer to the following.

This mode executes the test operation and adjustment of axes using an engineering tool.
This function transfers servo parameters. Servo parameters, which are controlled by servo amplifiers, can
be changed with a Simple Motion module.
This function is used to execute deceleration stop safety for other axes when the servo alarm occurs in the
servo amplifier MR-JE-B(F).
