Precautions During Operation and Running Warning Before installing the machine and starting operation, perform the switch and parameter settings appropriate to the machine. If you operate the machine without setting, it may cause accidental operation, malfunction or injury to people. Do not make extreme changes to the parameter settings. Otherwise, it may cause unstable operation, mechanical damage or injury. To avoid accidents, install a limit switch or stopper at the end of the movable part of the machine. Otherwise, it may cause damage or injury to the machine. Perform the test run with the servo motor fixed and disconnected from the machine. Otherwise, injury may occur.
Do not enter the operating range of the machine during operation. Otherwise, injury may occur. Do not touch the servo motor or the movable part of the machine during operation. Otherwise, injury may occur. Attention Please design a safety system to ensure safety even in the event of a fault such as a broken signal line. For example, a safety action is performed when the P-OT signal and N-OT signal are disconnected at the factory setting. Do not change the polarity of these signals. When overtravel occurs, the motor is not energized and the brake is released. If the servo motor is used for vertical drive, set the motor to enter the zero fixed state after it stops.
Also, 7 SD700 Series Servo Technical Manual Insufficient tightening may cause the cable connector to fall off during operation. Do not use the same sleeve for strong power cables (main circuit cables) and weak power cables (cables for input and output signals and encoder cables), or tie them together. If you do not put strong and weak cables in separate sleeves, keep a distance of 30cm or more between them when wiring. If they are too close together, the weak power cables may be interfered with and cause malfunction. Install the battery on either side of the upper unit or encoder cable.
If the battery is installed on the upper unit and encoder cable at the same time, a loop circuit will be formed between the batteries and the product will be damaged or burned. When connecting the battery, please pay attention to the polarity. A broken battery can cause the encoder to malfunction.
