NOTE l: Protective structure is based upon JEMI030 1977.
NOTE 2: The output voltage will decrease if input voltage decreases.
NOTE 3: Confirm with the motor manufacturer the moto6 maximum rpm when uring c motor
running at frequency higher than 50/60 Hz.
NOTE 4: When using the standard four pole motor. select the high starl torque (SLV) at the rated
voltage. (For details, contact the dealer you purchased the product.)
NOTE 5: Torque will be reduced when the base frequency exceeds 50/60 Hz.
The dynamic braking torque is about 607. for 055HF or about 50olo for 075HF when
the 400 V class RB2 x 2 se es f70 O or more) is used.
NOTE 6; According to the test method shown is JIS C 0911 (1984)
