Fluctuations In The Power Voltage And Frequency; Fig.3-1 Change Region Of The Voltage And Frequency - Ulvac DAT-50DA Instruction Manual

3.5 Fluctuations in the power voltage and frequency

Standard: General rules for rotating electrical machines
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).
