②
M/C signal cable
Cables with 68-pin, square connectors on both ends.
Connect the signal cable to the manipulator SIGNAL connector and controller M/C SIG-
NAL, respectively. Using the two fitting screws attached to the connectors, tighten down
the connectors so that they will not come loose.
③
Safeguard switch connection (REMOTE1)
Please be absolutely certain to erect a safety enclosure around the robot area.
Connect that safeguard switch to the input terminal of the REMOTE1 safeguard. Since
this input terminal is “normally closed,” the robot will not operate normally if the safeguard
switch is not installed.
Details of the connector are included in “4. REMOTE1” in this volume.
④
REMOTE2
Connect the optional operating unit (OPU-300 or OPU-320) to REMOTE2. Please refer
to the separate manual for the operating unit for details.
If the operating unit is not being used, connect a “normally closed” emergency stop switch
with the REMOTE2 connector that came as a standard accessory. If nothing is connected,
the robot will be in the Emergency Stop mode and will not function. Details concerning
necessary procedures when the operating unit is not being used appear in “5. When not us-
ing the operating unit” in this volume.
⑤
PE(F-GND) terminal connections
The PE terminal is for connection to the ground (frame ground).
We recommend connecting the PE terminal when several robots are used in a line or when
a peripheral control unit such as a sequencer is used in the system. Use wiring having a
diameter equal to or greater than AWG #16 to connect to the PE terminal.
⑥
TEACH port
Connect any one of the following units. If nothing is connected, the robot will be in the
Emergency Stop mode and will not function. The details of these connectors are included
in “3. Teach Port” in this volume.
z PC cable for SPEL Editor or SPEL for Windows (option)
z Teaching pendant TP-320 (option)
z TEACH port connector
„
SPEL Editor and SPEL for Windows are designed so that the robot is operated
from outside the safeguarded space for program development.
Be sure to use the teaching pendant with an enable switch and emergency stop
switch when performing the teaching operation within the safeguard space.
„
Use PC cable with an enable switch when you connect a personal computer to
the controller.
