To the voltage change and frequency change in Domain A,
in main rated values, it operates continuously, and can be
used practically convenient, and to the voltage change and
frequency change in Domain B, it shall operate with main
rated values and shall be used practically convenient.
However, operation with "it is convenient and safe is
maintained on "practical use, it means not resulting in the
grade which shortens a life remarkably, and the
characteristic, a temperature rise, etc. do not apply
correspondingly in the state of rating. Moreover, main
rating shows rated torque (N

m).
Connect the ground lead without exception at this time.
