1. To prevent electric shock, note the following: WARNING Before wiring or inspection, switch power off and wait for more than 15 minutes. Then, confirm the voltage is safe with voltage tester. Otherwise, you may get an electric shock. Connect the base unit and servo motor to ground. Any person who is involved in wiring and inspection should be fully competent to do the work. Do not attempt to wire for each unit and the servo motor until they are installed. Otherwise, you can obtain the electri

4. Additional instructions The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric shock, etc. (1) Transportation and installation CAUTION Transport the products correctly according to their weights. Stacking in excess of the specified number of products is not allowed. Do not carry the servo motor by the cables, shaft or encoder. Do not hold the front cover to transport each unit. Each unit may drop. Install the each unit in a load-bearing

(2) Wiring CAUTION Wire the equipment correctly and securely. Otherwise, the servo motor may misoperate. Do not install a power capacitor, surge absorber or radio noise filter (FR-BIF option) between the servo motor and drive unit. Connect the output terminals (U, V, W) correctly. Otherwise, the servo motor will operate improperly. Connect the servo motor power terminal (U, V, W) to the servo motor power input terminal (U, V, W) directly. Do not let a magnetic contactor, etc. intervene. drive

(4) Usage CAUTION Provide an forced stop circuit to ensure that operation can be stopped and power switched off immediately. Any person who is involved in disassembly and repair should be fully competent to do the work. Before resetting an alarm, make sure that the run signal of the servo amplifier is off to prevent an accident. A sudden restart is made if an alarm is reset with the run signal on. Do not modify the equipment. Use a noise filter, etc. to minimize the influence of electromagnetic
