When the internal interface power source P24-CM1 is used (Sink type wiring)

A)Turn control terminal 1 on. (In the initialization at factory before ship- ment, intelligent input terminal 1 is allocated to the reset RS terminal.)

B)Press STOP/RESET on the digital

operator. (This is effective only when an alarm occurs.)

C)Open the power receiving breaker of the inverter, and make sure that the Charge lamp on the control board goes out. (See page 3-1.) Then, close the power receiving breaker.

NOTE: When the control circuit terminal RS is used, never short-circuit RS-P24 (CM1*) for four seconds or more. Otherwise, a communication error

R-ERROR COMM<2> may occur (Although the digital operator display is

, the inverter is normal). When the above error occurs, open the RS termi- nal and press the operator key.

*: For sink type wiring

How to return to the initialization (state before shipment)

When returning the equipment to the initial state set at factory before shipment for some reason, see page 7-14.
