30010 RUNNING
This signal signifies that the job is running.
(Signifies that the job is running, system status
is waiting reserved start, or test run is running.)
This signal status is the same status as
[START] in the programming pendant.
30023 INTERMEDIATE START OK
This signal turns ON when the manipulator
operates. It turns OFF when the currently exe-
cuted line is moved with the cursor or when
editing operation is carried out after HOLD is
applied during operation. Therefore, this signal
can be used as a restart interlock after a HOLD
is applied. However, it also turns ON in the
teach mode and TEACH MODE SELECTED
signal must be referred together.
30011 SERVO IS ON
This signal signifies that the servo power is
turned ON, internal processing such as current
position creation is complete, and the system is
able to receive the START command. This sig-
nal turns OFF when the servo power supply
turns OFF. It can be used for NX100 status
diagnosis for an external start.
30024 IN CUBE 3
This signal turns ON when the current TCP lies
inside a pre-defined space (Cube 3). Use this
signal to prevent interference with other manip-
ulators and positioners.
30012 TOP OF MASTER JOB
This signal signifies that the execution position
is the top of the master job. This signal can be
used to confirm that the master job has been
called.
*1
30025 IN CUBE 4
This signal turns ON when the current TCP lies
inside a pre-defined space (Cube 4). Use this
signal to prevent interference with other manip-
ulators and positioners.
30013 ALARM/ERROR OCCURRED
This signal signifies that an alarm or an error
occurred. If a major error occurs, this signal
remains ON until the main power is turned
OFF.
30050
*4
WELD ON/OFF
Outputs a signal input from the interlock panel,
etc.considering the robot status.
30014 BATTERY ALARM
This signal turns ON to notify that the battery
requires replacing when the voltage drops from
the battery for backup memory of the encoder.
Major problems may result if memory data is
lost because of an expired battery. It is recom-
mended to avoid these problems by using this
signal as a warning signal.
30051
*3
WELD ERROR RESET
This signal commands the reset error status of
the Power Source. This is operated with the
programing pendant operation.
30015 to
30017
REMOTE/PLAY/TEACH MODE SELECTED
This signal notifies the current mode setting.
These signals are synchronized with the mode
select switch in the programming pendant. The
signal corresponding to the selected mode
turns ON.
30052 to
30056
*3
WELD CONDITION (Level signals)
1(1), 2(2), 4(3), 8(4), 16(5), 32(6), 64(7), 128(8)
Sets the welding conditions for the Power
Source.
The output format can be selected as binary or
discrete (bit number). It can handle up to 255
conditions. Most-significant bit is the parity bit
(when specified).
30020 IN CUBE 1
This signal turns ON when the current TCP lies
inside a pre-defined space (Cube 1). Use this
signal to prevent interference with other manip-
ulators and positioners.
*3
WELDING COMMAND
This signal outputs execution command signal
to the Power Source. This signal is not neces-
sary for a Power Source which is executed
using the WELDING CONDITION signal.
30021 IN CUBE 2
This signal turns ON when the current TCP lies
inside a pre-defined space (Cube 2). Use this
signal to prevent interference with other manip-
ulators and positioners.
*3
STROKE CHANGE1
SINGLE SOLENOID
DOUBLE SOLENOID
This is a signal, when a double stroke gun is
used, to change the open stroke of the welding
gun.
30022
WORK HOME POSITION (IN CUBE 32)
*2
This signal turns ON when the current TCP lies
inside a the work home position area. Use this
signal to evaluate whether the robot is in the
start position.
*3
GUN PRESSURE INSTRUCTION
This outputs a gun pressure instruction.
