Handling The I/O Checker - Yamaha DRCX User Manual

16-2-2 Handling the I/O Checker

This device connects to the I/O connector of the DRCX controller and is used for pseudo-input
(emulation) by means of switches and for input/output monitoring by LED display.
■ Connecting the I/O checker
1. Plug the connector marked "ROBOT I/O" into the I/O connector of the DRCX controller.
2. Plug the connector marked "JAE 50P" into connector CN1 on the right of the I/O Checker and
make sure it locks.
3. Plug the connector, which is normally connected to the I/O connector of the DRCX controller,
into connector CN2 on the left of the I/O Checker.

■ Operation method
1. The LED monitor turns on (lights) and off (goes out) in conjunction with the input and output.
2. The pseudo-input switch is on when set to the upper side and off when set to the lower side.
However, the INTERLOCK and EMG inputs are opposite; they are on when set to the lower
side and off when set to the upper side.
Thus, if all of the switches are set to the lower side at first, the unit can be used for pseudo-
input and as an I/O monitor.
3. The input changeover switch should be set to the EXTERNAL (upper) side to receive external
input from a PLC or a similar unit.
If the switch is set to the INTERNAL (lower) side, the switch signals on the I/O checker are
input to the controller. In either case, the input monitor is handled by means of LEDs.
