NOTE 1: Protective structure is based upon JEM1030-1977.

NOTE 2: The output voltage will decrease if input voltage decreases.

NOTE 3: Confirm with the motor manufacturer the motors maximum rpm when using a motor running at frequency higher than 50/60 Hz.

NOTE 4: When using the standard four-pole motor, select the high start torque (SLV) at the rated voltage (200 V class: 200, 220, 230 V; 400 V calss:400, 415, 440, 460 V).

(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 70% for 055LF or about 60% for 075LF when one of the 200 V class RB1 to RB3 (17Ω or more) is used at the shorttime rating or about 60% for 055HF or about 50% for 075HF when the 400 V class RB2 × 2 series

(70 Ω or more) is used.

NOTE 6: According to the test method shown is JIS C 0911 (1984).
