1. FUNCTIONS AND CONFIGURATION
1.1 Introduction
The MR-J3- T CC-Link compatible servo amplifier can supp ort the CC-Link communication functions. Up to 42
axes of servo amplifiers can be controlled/moni tored from the programmable controller side.
As the servo, it has the function to perform positioning operation by merely setting the positi on data (target
positions), servo motor speeds, acceleration a nd deceleration time constants, etc. to poin t tables as if setting
them in parameters. The servo amplifier is t he most appropriate to configure a program-f ree, simple positioning
system or to simplify a system, for exam ple.
There are 31 points of point tables to be used when 1 station is occupied and 255 points when 2 stations are
occupied.
All servo motors are equipped with an absolu te position encoder as standard. An absolute position detection
system can be configured by merely adding a b attery to the servo amplifier. Once the hom e position has been
set, home position return is not required at power on, alarm occurrence, etc.
The MR-J3-T is made easier to use and higher i n function by using it with the MR Configurator .
1.1.1 Features of CC-Link communication functions
(1) Fast communication
Fast communication can be made by cyclic transm ission of not only bit data but also word data.
(a) The highest communication speed is 10Mbps .
(b) The broadcast polling system ensures as high as 3.9ms to 6.7ms even at the maximum link scan
(10Mbps).
(2) Variable communication speed/distance s ystem
Selection of speed/distance allows use in a wide range of areas from a system requiring high speed to a
system requiring long distance.
(3) System fault prevention (station separatin g function)
Because of connection in the bus system, any remote or local station that has become faulty due to power-
off or the like does not affect communications with normal remote and local stations.
In addition, use of the two-piece terminal block allows the unit to be change d during data link.
(4) Factory Automation compatible
As the remote device stations of CC-Link , the servo amplifiers share a link s ystem and can be
controlled/monitored with programmable control ler user programs.
From the programmable controller side, the runnin g speed, acceleration/deceleration time constant and
other settings of servo motors can be changed/ch ecked and the servo motors started and stopped .
