This function returns the setting data stored in the buffer memory/internal
memory and flash ROM/internal memory (nonvolatile) of RD77MS to the
default values.
The following two methods can be used.
(1) Method using a program
(2) Method using an GX Works3
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.
(1) Method using a program
(2) Method using an GX Works3
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 external input signals of the axes can be arbitrarily assigned to the 20
terminals of the external input connection connector of RD77MS.
This function monitors start history and current value history of all axes.
This function executes the positioning control of RD77MS 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 RD77MS
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 SSCNETIII cables.
Allows to replace a module without stopping the system. For procedures for
the online module change, refer to the following.
