Data
1 frame (11 bits)
Reads the items in "Display all", the monitor function of MR Configurator2,
such as the servo motor speed and droop pulses.
Reads and writes data from/to parameters.
Reads and writes point table data.
Reads alarm numbers that currently exist.
Reads the history of up to 16 alarms.
Reads the parameter number at occurrence of a parameter error.
Reads the point table number at occurrence of a point table error.
Reads the ON/OFF state of external I/O signals and the status of the I/O
devices
Reads the servo amplifier model and software version.
By accessing to holding registers which are assigned like the address
assignment of CiA 402 drive profile, the servo motors are driven.
