1. FUNCTIONS AND CONFIGURATION
1. FUNCTIONS AND CONFIGURATION
1.1 Introduction
The MR-J3axes of servo amplifiers can be controlled/monitored from the programmable controller side.
As the servo, it has the function to perform positioning operation by merely setting the position data (target
positions), servo motor speeds, acceleration and deceleration time constants, etc. to point tables as if setting
them in parameters. The servo amplifier is the most appropriate to configure a program-free, simple positioning
system or to simplify a system, for example.
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 absolute position encoder as standard. An absolute position detection
system can be configured by merely adding a battery to the servo amplifier. Once the home 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 in 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 transmission 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
(2) Variable communication speed/distance system
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 separating function)
Because of connection in the bus system, any remote or local station that has become faulty due to poweroff 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 changed during data link.
(4) Factory Automation compatible
As the remote device stations of CC-Link, the servo amplifiers share a link system and can be
controlled/monitored with programmable controller user programs.
From the programmable controller side, the running speed, acceleration/deceleration time constant and
other settings of servo motors can be changed/checked and the servo motors started and stopped.
T CC-Link compatible servo amplifier can support the CC-Link communication functions. Up to 42
(10Mbps).
