1. SUMMARY
1.2 Features
The position board has the following features.
(1) Structuring of SSCNET
/H communication servo system by computer control
The position board can be directly connected to the Mitsubishi servo amplifiers of MR-J4-B series using
SSCNET
/H.
(a) By connecting the position board and servo amplifier and servo amplifiers with a high speed
synchronous network by SSCNET
/H, the reduction of wiring is achieved. The maximum distance
between the position board and servo amplifier, or servo amplifier and servo amplifier for the SSCNET
cable on the same bus is 100(328.08)[m(ft.)]. This increases flexibility at system design.
(b) By using SSCNET
cable (optical communication), the influence of electromagnetic noise etc. from
servo amplifiers and such is reduced.
(c) The servo parameters can be set on the position board side and written to the servo amplifier, or read
from the servo amplifier using the SSCNET communication.
(d) The current feedback position and error description contained in the servo can be checked by the dual
port memory of the position board.
(e) Communication between MR Configurator2 and the servo amplifiers is possible via the position board
USB.
(2) Programming in C programming language with the API library
Positioning control for the servo in C programming language is enabled with the API library included with
the Position Board Utility2 (MRZJW3-MC2-UTL).
(3) Supports event-driven programming
The host controller is notified by interrupt via PCI bus when the conditions for an interrupt such as passing
through a preset point or positioning complete are met. The user program can create event-driven
programs according to interrupt factors.
(4) High-speed operation starting time
High-speed operation starting time within the control cycle (0.22ms fastest) is achieved for the maximum
number of synchronous startup axes or less.
