E6581301

- Warning -

• When switching to commercial power, make sure that the direction in which the motor rotates when operated on commercial power agrees with the forward direction when operated via the inverter.

• Do not select any option (￿￿￿￿=￿) of ￿￿￿￿ (reverse rotation prohibition selection) that prohibits forward rotation. Or it becomes impossible to switch to commercial power, because the motor cannot rotate in the forward direction.

!Function

 

 

 

 

 

 

 

 

 

Using feedback signals (4 to 20mA, 0 to 10V) from a detector, process control can be exercised, for

 

 

 

example, to keep the airflow, amount of flow or pressure constant.
