Item Description
Input voltage
Model Name (Type)
400 V class
Protective structure is based upon JEM1030-1977.
The output voltage will decrease if input voltage decreases.
Confirm with the motor manufacturer the motors maximum rpm when using a motor
running at frequency higher than 50/60 Hz.
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.)
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 (17
Ω
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.
According to the test method shown is JIS C 0911 (1984).
