1. FUNCTIONS AND CONFIGURATION

1.1 Introduction

When used with the MR-J2S-T01 CC-Link option unit, the MR-J2S- CP-S084 CC-Link compatible servo
amplifier can support the CC-Link communication functions. Up to 42 axes of servo amplifiers can be
controlled/monitored from the PLC side.
As the servo, it is based on the MR-J2S-CP AC servo amplifier with built-in positioning functions and 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 3 points of point tables as standard, and they can be increased up to 31 points by using the
optional servo configuration software.
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-J2S-CP-S084 AC servo amplifier with positioning function is made easier to use and higher in
function by using it with the servo configuration software.

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
(10Mbps).
(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
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 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 PLC user programs.
From the PLC 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.
