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 masses. 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 p

(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 a emergency 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 electromagne
