Part 1 Installation
2. Safety Circuit for PX Type (Standard Specification) Controller
The PX type controller has a built-in drive source cutoff circuit just like IAI’s other controllers.
The drive source cutoff circuit consists of a relay and conforms to safety category B. If your equipment
must meet a higher safety category, use the QX type (global specification) controller explained later.
Connect the control power supply and motor power supply to the same power source and also turn on/off
the control power supply and motor power supply at the same time.
The teaching pendant port can be connected to either an IAI’s standard teaching pendant or ANSI
teaching pendant. Note, however, that redundant safety circuits cannot be configured even if an ANSI
teaching pendant is used.
Set the teaching pendant type switch located above the teaching pendant connector to the position
appropriate for the teaching pendant used. Set the switch to the left for an ANSI teaching pendant, or to
the right for IAI’s standard teaching pendant.
Note: If the teaching pendant type switch is not set properly, the safety gate switch will not function.
The emergency stop line and enabling line are driven by the controller’s internal power supply. It should
be noted that the safety circuit cannot be driven by an external power source.
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.
