Instructions Manual
Overview1.
1-1. Features
The AL- series is a high speed serial communication system of original controlling the flexible stepping motor,●Ⅱ
servo motor which can cope easily as well and I/O in the decentralization of the device and supporting axial addition.
The AL- series is an insulation type high-speed serial communications of 20 Mbps/50 m or 10 Mbps/100 m.・Ⅱ
The wiring for the personal computer system can be omitted with USB of a personal computer general-purpose port.
The shift of board controller C-VX870 series Device-function for PCI made of our company and the USB series・()
Device-function and Unit-function is easy depending on the device driver function for Windows.()
The status of four axis batch reading and the command of four axis batch execution by the Unit-function is possible.●This Unit-function can perform a unit and AL- interface by one function execution from an application.Ⅱ
By this,
The time crunch can be done compared with accessed Device-function of each axis and I/O-function of・each I/O port.
The Unit-function writing suppresses the difference at time until it instructs time each axis and each I/O output・()
signal.
The Unit-function can reduce the load of the application.・It supports the Device-function, and can use the Device-function.・The Unit-function can be used together with the Device-function and the I/O-function.・

AL- The error total number detected in the AL- communication after the power supply isⅡⅡ
communication turned on can be read.
It is possible to use it for the evaluation of the communication environment.
When retrying is detected, it counts as an error.
The error total number can be counted 65535 times or less.
More than it do not update a count.
Clear of error total number・The value in which the error total number is counted can be cleared to 0.
Retry・It is a function to evade the stagnation of the entire system by retrying it when the influence
of the noise etc. is given to AL- communications.Ⅱ
The number of retrying is set by an Environment-set-function.
When retrying is made effective and the communication abnormality is detected, retrying is
automatically executed.
The setting of retrying is possible by the range from 0 non-retry to 3.()
3 Initialize Auto transmission of initialization・The master carries out initialization for all slaves automatically when user carries out an
Environment-set-function to a master.
Interlock・When an Environment-set-function is executed from the application, master executes
initialization a request to each slave.()
The slave product of the AL- series doesn't accept other requests until the initial-requestⅡ
sent from master is received after the power supply is turned on.
When other requests are received, an initial error is returned.
As a result, master notifies the application the answer back.
When the internal logic on the slave side was reset by the power failure etc. momentarily,
operation by the improper data can be stopped.
Please execute to master an Environment-set-function, after turning on slave's power supply.
4 Backup The backup can easily edit the parameter of each slave from USB by initialization editing soft・ware by the OFFLINE, and a master can back up the edited parameter Initial data .()
The initial data which a master backs up transmit a message for each slave at the time of the
practice of the Initial-data-transmission-function automatically.
5 ONLINE/OFFLINE As for the master, access are possible from ONLINE user application and OFFLINE・()
Function support application .()
The OFFLINE is a adjustment tool to offer the application that the function used USB to
enable machine adjustment without the application program development of the user
immediately for.
* ONLINE and OFFLINE cannot be controlled at the same time.
Execute it after stopping the application from ONLINE when you control from OFFLINE.
