TEACH LOCK Key
The TEACH LOCK key locks operation of the robot with the programming
pendant. Operation is not possible from the playback panel or operator station.
Servo power can not be applied in TEACH mode unless TEACH LOCK is ON.
RS-232C Serial Port
This 9-pin serial port is used for data communication between the XRC and a
floppy disk controller (FC1 or FC2), FDE (Floppy Disk Emulator) software, or
other form of communication (see Figure 3-4).
ENABLE Switch
The ENABLE switch (see Figure 3-5) is a three-position switch located on the left
rear of the programming pendant. It is a safety feature that controls servo power
while in TEACH mode. When pressed in, this switch enables servo power to be
turned on. However, should the operator release the switch, or grasp it too tightly,
servo power is immediately disabled, preventing further robot movement.
