HARDWARE REFERENCE MANUAL
WARNING
Never short-circuit the positive and negative terminals of the bat-
teries, charge the batteries, disassemble them, deform them by
applying pressure, or throw them into a fire.
The batteries may explode, combust or leak liquid.
WARNING
Fail-safe measures must be taken by the customer to ensure
safety in the event of incorrect, missing, or abnormal signals
caused by broken signal lines, momentary power interruptions, or
other causes.
Not doing so may result in serious accidents.
WARNING
Emergency stop circuits, interlock circuits, limit circuits, and similar
safety measures must be provided by the customer as external cir-
cuits, i.e., not in the Trajexia motion controller.
Not doing so may result in serious accidents.
WARNING
When the 24 VDC output (I/O power supply to the TJ2) is over-
loaded or short-circuited, the voltage may drop and result in the
outputs being turned off.As a countermeasure for such problems,
external safety measures must be provided to ensure safety in the
system.
WARNING
The TJ2 outputs will go off due to overload of the output transistors
(protection).As a countermeasure for such problems, external
safety measures must be provided to ensure safety in the system.
