7.2 Power Supply Contactor Sequence Circuit Board (JANCD-NTU01-#)7-6" Connection for External Axis Overrun (EXOT)With a unit of standard specifications without an external axis, the external axis overrun inputsignal is not used. In this case, a jumper cable is connected as shown in the following figure.If an overrun input signal for an axis other than manipulator axes, for example the externalaxis, is required, connect the signal input circuit in the following manner.For safe reason, a dual circuits are used for the external axis overrun signal input. Connectthe external axis overrun signal so that both input signals are turned ON or OFF at the sametime. If only one signal is turned ON, an alarm occurs.1. Remove the jumper cable between the connectors CN06-5 and -6 and between theconnectors CN06-7 and -8 of the JZRCR-NTU##-# power supply contactor unit.2. Connect the external axis overrun wiring between the connectors CN06-5 and -6 andbetween the connectors CN06-7 and -8 of the JZRCR-NTU##-# contactor unit.Fig. 3 Connection for External Axis Overrunï Remove jumper cable installed on system input signal before connect-ing the input signal lines.Failure to observe this caution could lead to injury or mechanical failure.CAUTIONNX100CN06-5-6-7-8+24V2EXOT1EXOT2024VRemove the jumper cableTurn ON/OFFat the same timeExternal axis overrunPower supply contactor unitJZRCR-NTU!!
