Specifications

1-2
(1) Features of the communication function
1) Fast communication
Cyclic transmission of not only bit data but also word data can be made to enable fast communication.
(a) 10Mbps high-speed communication can be achieved
(b) The adoption of the broadcast polling system ensures high speed of max. 3.9ms to 6.7ms link scan.
2) Communication speed/distance variable system
Selection of the speed and distance enables use in a wide range from a system that demands high speed
to a system that requires a long distance.
3) Prevention of system fault (station separation function)
The bus connection system does not affect communications with normal remote and local stations if any
remote or local station becomes faulty at power-off, etc.
The two-piece terminal block allows the unit to be changed during a data link.
4) Compatibility with Factory Automation
Factory Automation can be easily applied to servo amplifiers by sharing a link system as remote device
stations of CC-Link and controlling and monitoring them with the user program of the PLC.
Various settings of motor speeds, acceleration/deceleration times, etc. can be changed and confirmed
from the PLC.
(2) Features of the servo section
In addition to the basic performance of the MR-J2S, etc., the servo section has the following positioning function.
1) Positioning using up to 31 point tables.
2) Position data can be specified directly from outside (only when two stations are occupied)
3) Speed data can be specified directly from outside (only when two stations are occupied)
4) Absolute position system compatibility
5) Eight different home position return methods
(3) System configuration
Operations using the MR-J2S-CP-S084 will be described.
Using CC-Link, a system can be configured freely from a single-axis system to an up to 42-axis system.
Further, external input signals can be assigned to the CN connector pins by setting parameters Pr. 116, 117 and 118.
Data for operation consists of the following point table.
