Part 1 Installation
3. Safety Circuit for QX Type (Global Specification) Controller
The global controller has no internal drive source cutoff circuit so that the user can configure a desired
drive source cutoff circuit externally to the controller to conform to the required safety category.
The safety circuit consists of two circuits: the emergency stop (EMG) circuit and enable (ENB) circuit.
Each circuit adopts a redundant design, so a safety circuit conforming to a higher safety category of up to
level 4 can be configured using an external drive source cutoff circuit.
Since this controller has no built-in drive source cutoff circuit, be sure to install a drive source cutoff circuit
in the motor power circuit. It is recommended that the control power supply be wired from the same power
source as the motor power supply at a point before the drive-source cutoff part is connected.
Please note that IAI is not liable for any losses arising from a malfunction of the safety circuit configured
by the user.
The ANSI safety standard can be met only when an ANSI teaching pendant is connected to the teaching
port.
The redundant emergency stop lines and enabling lines are designed with the assumption that they will be
driven by a power source external to the controller. Note, however, that the inputs to the contacts that
provide for emergency stop action and enabling action operate on the internal power supply.
Do not use the internal power supply provided for the system I/O connector for any other purpose. It may
damage the equipment or cause it to malfunction.
The tables below list the signals and wiring methods of the safety circuit interface connector. The
connector pin assignments and internal circuit components are the same as those of the standard
specification.
