Strict observance of these warning and caution indications are a MUST for preventing accidents, which could result in bodily injury and substantial property damage. Make sure you fully understand all definitions of these terms and related symbols given below, before you proceed to the text itself.
1. Introduction This section provides safety precautions to be observed during installation, teaching, inspection, adjustment, and maintenance of the robot. 2. Installation Precautions 2.1 Insuring the proper installation environment 2.1.1 For standard type The standard type has not been designed to withstand explosions, dust-proof, nor is it splash-proof.
SAFETY PRECAUTIONS 2.3 Control devices outside the robot's restricted space The robot controller, teach pendant, and operating panel should be installed outside the robot's restricted space and in a place where you can observe all of the robot’s movements when operating the robot controller, teach pendant, or operating panel. 2.4 Positioning of gauges Pressure gauges, oil pressure gauges and other gauges should be installed in an easy-to-check location. 2.
2.8 Setting-up the safety fence or enclosure A safety fence or enclosure should be set up so that no one can easily enter the robot's restricted space. If it is impossible, utilize other protectors as described in Section 2.9. (1) The fence or enclosure should be constructed so that it cannot be easily moved or removed. (2) The fence or enclosure should be constructed so that it cannot be easily damaged or deformed through external force. (3) Establish the exit/entrance to the fence or enclosure.
SAFETY PRECAUTIONS 2.10 Setting the robot's motion space The area required for the robot to work is called the robot's operating space. If the robot’s motion space is greater than the operating space, it is recommended that you set a smaller motion space to prevent the robot from interfering or disrupting other equipment. Refer to the "INSTALLATION & MAINTENANCE GUIDE." 2.11 No robot modification allowed Never modify the robot unit, robot controller, teach pendant or other devices. 2.
3. Precautions while robot is running Warning Touching the robot while it is in operation can lead to serious injury. Please ensure the following conditions are maintained and that the cautions listed from Section 3.1 onwards are followed when any work is being performed. 1) Do not enter the robot's restricted space when the robot is in operation or when the motor power is on.
SAFETY PRECAUTIONS 3) Maintaining worker position and stance Position and stance that enables the worker to confirm normal robot operation and to take immediate refuge if a malfunction occurs. 4) Implementation of measures for noise prevention 5) Signaling methods for workers of related equipment 6) Types of malfunctions and how to distinguish them Please ensure "working regulations" are appropriate to the robot type, the place of installation and to the content of the work.
3.4 Inspections before commencing work such as teaching Before starting work such as teaching, inspect the following items, carry out any repairs immediately upon detection of a malfunction and perform any other necessary measures. (1) Check for any damage to the sheath or cover of the external wiring or to the external devices. (2) Check that the robot is functioning normally or not (any unusual noise or vibration during operation). (3) Check the functioning of the emergency stop device.
SAFETY PRECAUTIONS 3.8 Precautions in repairs (1) Do not perform repairs outside of the designated range. (2) Under no circumstances should the interlock mechanism be removed. (3) When opening the robot controller's cover for battery replacement or any other reasons, always turn the robot controller power off and disconnect the power cable. (4) Use only spare tools specified in this manual. 4. Daily and periodical inspections (1) Be sure to perform daily and periodical inspections.

2.3 Types and General Information about I/O Signals This section describes the I/O signals for the Robot Controller. The I/O signals are grouped into user I/O signals and system I/O signals. User I/O signals are compatible with conventional signals, including the pin pattern, in compatible mode. Note that the connector pin meanings are different between standard mode and compatible mode. Some of the signal lines used for user I/O in compatible mode are used for system input in standard mode.
2.3.2 Compatible Mode In the compatible mode, the input and output points are arranged in disregard of compatibility with conventional VS series robots. The table below lists the types of I/O signals used in compatible mode. Types of I/O Signals Used in Compatible Mode Fixed by system Type No. of points Function System input 22 Inputs to turn ON the power to the robot from the external device (PLC), start CAL or select and start a program instead of operations by the operating panel or teach pendant.
2.4 Using User I/O Signals (common to both modes) To use user I/O signals you need to first declare, in the program, the use of user I/O as I/O type variables with a DEFIO command. Next, access the user I/O by writing it to the I/O type variables or reading it. 2.4.1 I/O Type Variable Declaration I/O type variables are classified into I/O type global variables that are available without any declaration, and I/O type local variables that are not available without a declaration. 2.4.
2.4.5 User Output Commands There are three types of user output commands, SET, RESET and OUT. The SET and RESET commands turn ON and OFF all user outputs specified by I/O type variables. The OUT command outputs data to a specified user output. • SET Command The SET command turns ON all user outputs specified by I/O type variables. For further information about the SET command, refer to the PROGRAMMER'S MANUAL (I), Chapter 13, Section 13.1 "SET.
