Safety warnings and precautions
Caution
Do not pull on the cables or bend the cables beyond their natural
limit. Doing so may break the cables.
Caution
Before touching the system, be sure to first touch a grounded
metallic object in order to discharge any static build-up.
Otherwise it might result in a malfunction or damage.
Caution
UTP cables are not shielded. In environments that are subject to
noise use a system with shielded twisted-pair (STP) cable and
hubs suitable for an FA environment.
Do not install twisted-pair cables with high-voltage lines.
Do not install twisted-pair cables near devices that generate noise.
Do not install twisted-pair cables in locations that are subject to
high humidity.
Do not install twisted-pair cables in locations subject to excessive
dirt and dust or to oil mist or other contaminants.
Caution
Use the dedicated connecting cables specified in operation manu-
als to connect the Units.
Using commercially available RS-232C computer cables may
cause failures in external devices or the Motion Control Unit.
Caution
Outputs may remain on due to a malfunction in the built-in transis-
tor outputs or other internal circuits.
As a countermeasure for such problems, external safety measures
must be provided to ensure the safety of the system.
HARDWARE REFERENCE MANUAL
Caution
The TJ2 will start operating in RUN mode when the power is
turned on and if a BASIC program is set to Auto Run mode.
Caution
Always check the "Status-Words" of each GRT1-ML2 coupler.
Not doing so can lead to missing or incorrect I/O data.
Caution
Always check the status of the connected MECHATROLINK-II
devices in a BASIC program.
Not doing so may result in an unexpected operation.
Caution
The TJ1-CORT unit is developed to exchange I/O data between
the Trajexia system and a CANopen network.
The TJ1-CORT is not able to exchange motion commands.
Using the TJ1-CORT to exchange motion commands may result in
unexpected operation.
WARNING
Although the TJ2-MC64 in most cases is backwards compatible
with TJ1-MC__, applications written for TJ1-MC__ must be tested
carefully when running on TJ2-MC64.
Not doing so may result in unexpected operation.
WARNING
When using multiple TJ1-ML__ units, do not swap the MECHA-
TROLINK-cables. This can result in different axis allocation. This
can result in serious injury and/or significant damage.
