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
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), near-point dog signal (DOG), and stop signal
(STOP)).
The function enables the assignment of external input signal of each axis to any terminals of 20 points of
the external input connection connector on 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.
This function enables to check the error history 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.
Allows to replace a module without stopping the system. For procedures for the online module change,
refer to the following.
MELSEC iQ-R Online Module Change Manual
This function is used to execute deceleration stop safety for other axes when the servo alarm occurs in the
servo amplifier MR-JE-B.
