MECHATROLINK-
III
and Communications Settings
The
Σ
-V-SD drivers were developed for machine tools. MECHATROLINK-III servo profile commands are
used to interface the servo drive and the host controller.
The host controller implements the ASIC (JL-100/JL-101) for MECHATROLINK-III communications and is
connected to the CPU by a bus connection.
When the host controller is used to control the servo, processing for the host controller is performed in real
time.
While there are many compatible real-time operating systems, an ASIC access driver for MECHATROLINK-
III communications is installed and the servo is controlled through access functions.
Refer to the
MECHATROLINK-III Communication ASIC JL-100/JL-101 (C1 Master) Access Driver
(Manual
No.: MMA TDEP 024A)
for details on access functions.
2.1.1
MECHATROLINK-
III
Initial Settings
You can download the master (C1) access drivers for the MECHATROLINK-III communications ASIC to
install in the host controller from the following website.
URL: http://www.mechatrolink.org/
You can also download sample application examples for the master (C1) from the above website.
Follow the C source files and the instructions from this website to install the drivers on the host controller.
The data bus width (BWDT) between the CPU and communications ASIC and the endian configuration
(ENDIAN) must also be set on the host controller.
Set the BWDT and ENDIAN pin connections on the communications ASIC and the access driver settings cor-
rectly.
Refer to the
MECHATROLINK-III Communication ASIC JL-100/JL-101 Hardware User’s Manual
(Manual
No.: MMA TDEP 019A)
for details on BWDT and ENDIAN pin connection settings.
The following two access drivers for communications ASIC for master (C1) are available depending on the
endian.
• M-III_driver_mst_16 bit_big_ver.1.20: For big endian, 16-bit bus connection
• M-III_driver_mst_ver.1.20: For little endian, 16-bit bus connection; little endian, 32-bit bus connection; or
big endian, 32-bit bus connection
Install the header files according to the endian type of your system.
Refer to the
MECHATROLINK-III Communication ASIC JL-100/JL-101 (C1 Master) Access Driver
(Manual
No.: MMA TDEP 024A)
for details on the access drivers.
2.1.2
Communications Settings for the Master Station
You must set the values in the JL100_USER_PAR and JL100_USER_IOMAP data structures in the access
driver at the master station.
To configure the system environment settings, set the JL100_USER_PAR and JL100_USER_IOMAP data
structures in the communications ASIC.
