    SAFETY PRECAUTIONS (Please read these instructions before using this equipment.) Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety to handle the product correctly. The precautions given in this manual are concerned with this product only. Refer to the user's manual of the CPU module to use for a description of the PLC system safety precautions.
  • Page 4 For Safe Operations 1. Prevention of electric shocks DANGER Never open the front case or terminal covers while the power is ON or the unit is running, as this may lead to electric shocks. Never run the unit with the front case or terminal cover removed. The high voltage terminal and charged sections will be exposed and may lead to electric shocks.
  • Page 5 3. For injury prevention CAUTION Do not apply a voltage other than that specified in the instruction manual on any terminal. Doing so may lead to destruction or damage. Do not mistake the terminal connections, as this may lead to destruction or damage. Do not mistake the polarity (+ / -), as this may lead to destruction or damage.
  • Page 6 CAUTION The system must have a mechanical allowance so that the machine itself can stop even if the stroke limits switch is passed through at the max. speed. Use wires and cables that have a wire diameter, heat resistance and bending resistance compatible with the system.
  • Page 7 DANGER The input devices and data registers assigned to the link will hold the data previous to when communication is terminated by an error, etc. Thus, an error correspondence interlock program specified in the instruction manual must be used. Use the interlock program specified in the intelligent function module's instruction manual for the program corresponding to the intelligent function module.
  • Page 8 CAUTION Transport the product with the correct method according to the mass. Use the servomotor suspension bolts only for the transportation of the servomotor. Do not transport the servomotor with machine installed on it. Do not stack products past the limit. When transporting the module or servo amplifier, never hold the connected wires or cables.
  • Page 9 CAUTION When not using the module for a long time, disconnect the power line from the module or servo amplifier. Place the module and servo amplifier in static electricity preventing vinyl bags and store. When storing for a long time, please contact with our sales representative. Also, execute a trial operation.
  • Page 10 CAUTION Correctly and securely wire the wires. Reconfirm the connections for mistakes and the terminal screws for tightness after wiring. Failing to do so may lead to run away of the servomotor. After wiring, install the protective covers such as the terminal covers to the original positions. Do not install a phase advancing capacitor, surge absorber or radio noise filter (option FR-BIF) on the output side of the servo amplifier.
  • Page 11 (5) Trial operation and adjustment CAUTION Confirm and adjust the program and each parameter before operation. Unpredictable movements may occur depending on the machine. Extreme adjustments and changes may lead to unstable operation, so never make them. When using the absolute position system function, on starting up, and when the module or absolute position motor has been replaced, always perform a home position return.
  • Page 12 Note that when the reference axis speed is designated for interpolation operation, the speed of the partner axis (2nd axis, 3rd axis and 4th axis) may be larger than the set speed (larger than the speed limit value). Use the units with the following conditions. 1) QD77MS/QD77GF Item Conditions Input power According to each instruction manual.
  • Page 13 (7) Corrective actions for errors CAUTION If an error occurs in the self diagnosis of the module or servo amplifier, confirm the check details according to the instruction manual, and restore the operation. If a dangerous state is predicted in case of a power failure or product failure, use a servomotor with an electromagnetic brake or install a brake mechanism externally.
  • Page 14 CAUTION Before performing online operations (especially, program modification, forced output, and operating status change) for the running CPU module on another station from GX Works2 over CC-Link IE Field Network, read relevant manuals carefully and ensure the safety. Improper operation may damage machines or cause accidents. Do not disassemble or modify the modules.
  • Page 15 CAUTION When the module or absolute position motor has been replaced, carry out a home position return operation using the following method, otherwise position displacement could occur. After writing the servo data to the Simple Motion module using programming software, switch on •...
