1. To prevent electric shock, note the following WARNING Before wiring or inspection, turn off the power and wait for 15 minutes or more (20 minutes or for drive unit 30kW or more) until the charge lamp turns off. Then, confirm that the voltage between P( ) and N( ) (L and L is safe with a voltage tester and others. Otherwise, an for drive unit 30kW or more) electric shock may occur. In addition, always confirm from the front of the servo amplifier (converter unit), whether th

(3) Test run adjustment CAUTION Before operation, check the parameter settings. Improper settings may cause some machines to perform unexpected operation. The parameter settings must not be changed excessively. Operation will be insatiable. (4) Usage CAUTION Provide an external 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. B

(5) Corrective actions CAUTION When it is assumed that a hazardous condition may take place at the occur due to a power failure or a product fault, use a servo motor with an electromagnetic brake or an external brake mechanism for the purpose of prevention. Configure the electromagnetic brake circuit so that it is activated not only by the servo amplifier (drive unit) signals but also by an external forced stop (EM1). Contacts must be open when Circuit must be servo-off, when
