SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. The instructions given this manual are concerned with this product. Refer to the User’s Manual of the CPU module in use for details on the safety instructions for the programmable logic controller system.
[DESIGN PRECAUTIONS] WARNING Provide a failsafe circuit to ensure that the system as whole can continue to function safely even if there is an external power supply fault or PLC failure. Otherwise there will be danger of accidents due to erroneous outputs or misoperation.
[WIRING PRECAUTIONS] CAUTION Ground the FG terminal using third class grounding or higher exclusively for the PLC. If you do not, the PLC will malfunction. Before connecting wires to the PLC, check the rated voltage and the terminal arrangement. Connecting power of a different voltage or wiring incorrectly will result in fire or failure.
CONDITIONS OF USE FOR THE PRODUCT (1) Mitsubishi programmable controller ("the PRODUCT") shall be used in conditions; i) where any problem, fault or failure occurring in the PRODUCT, if any, shall not lead to any major or serious accident; and ii) where the backup and fail-safe function are systematically or automatically provided outside of the PRODUCT for the case of any problem, fault or failure occurring in the PRODUCT.
MELSEC A series compact building block type PLC CPU (hereafter called the “PLC CPU”) A1S68DAV is used to convert incoming digital values (16-bit signed binary data) which are set with the PLC CPU to analog values (voltage outputs ranging from -10V to 10V).
6ms. *2 : The weight in hardware version “F” or earlier is 0.28kg. How to check the hardware version The hardware version for the A1S68DAV/DAI can be checked on the label on the front of the module. 1S68DA Software Version...
3. Nomenclature and Settings The name of each part of the A1S68DAV/DAI is indicated below. 1S68DAV 1S68DAI HLD/CLR HLD/CLR (FG) (FG) Remark In hardware version “F” or earlier, the RUN LED is positioned 6mm left from the one of hardware version “G” or later.
Filled out to indicate the application of each terminal 4. Handling 4.1 Caution on handling (1) The case module of the A1S68DAV/DAI is made of resin: do not drop is or subject it to strong impact. (2) Do not remove the printed circuit board from the case.
This will increase susceptibility to noise and the effects of surges and induction. (2) Ground the shielding of shielded wires and shielded cables at one point. 5.2 Module connection example (1) An example of the wiring to external devices in the case of an A1S68DAV is shown below. A1S68DAV Motor driver, etc.
(2) An example of the wiring to external devices in the case of an A1S68DAI is shown below. A1S68DAI Motor driver, etc. converter 600k circuit Motor driver, etc. converter 600k circuit *1: Use two-core shielded wiring (twisted). *2: If noise or ripple is generated by the external wiring, connect a 0.1 to 0.47μF (25V or more voltage resistance parts) capacitor to the input terminal of the external device.
