Handling Precautions
The explanations provided in this manual are limited to procedures of serial communication.
Refer to the operation manual supplied with the ROBO Cylinder Controller (hereinafter referred
to as RC controller) for other specifications, such as control, installation and connection.
Caution
(1) Make sure to follow the usage condition, environment and specifications ranges of
the product.
Not doing so may cause a drop in performance or malfunction of the product.
(2) If any address or function not defined in this specification is sent to an RC
controller, the controller may not operate properly or it may implement unintended
movements. Do not send any function or address not specified herein.
(3) RC controllers are designed in such a way that once the controller detects a break
(space) signal of 150 msec or longer via its SIO port, it will automatically switch
the baud rate to 9600 bps.
On some PCs, the transmission line remains in the break (space) signal
transmission mode while the communication port is closed. Exercise caution if one
of these PCs is used as the host device, because the baud rate in your RC
controller may have been changed to 9600 bps.
(4) Set the baud rate and other parameters using IAI’s PC software or other dedicated
teaching tool.
(5) If the controller is used in a place meeting any of the following conditions, provide
sufficient shielding measures. If sufficient actions are not taken, the controller may
malfunction:
[1] Where large current or high magnetic field generates
[2] Where arc discharge occurs due to welding, etc.
[3] Where noise generates due to electrostatic, etc.
[4] Where the controller may be exposed to radiation
(6) When performing wiring tasks and inserting/extracting connectors in/from sockets,
make sure that the power supplies of the host and each RC controller are turned
off. Carrying out such tasks with the power supplies turned on may result in
electric shock and/or damage to parts.
