※Totally enclosed fan cooled motors in conformance with JIS C 4210 for 0.2kW･0.4kW motors, and JIS C 4213 for motors over 0.75 kW.（made by Hitachi Industrial Equipment Systems）

※Motor input power sources are three phase, AC 200V/50Hz、AC200V・AC220V/60Hz.

※For the brake motor's braking frequency tolerance, please refer to the design's points for confirmation pages. More detailed frequency data depends on load conditions, so please confirm through selective calculation.

Options of BMS Models

**Models with Motor Terminal Blocks Mounted in Reverse *Made-to-order Parts**

Option symbol: G
There may be cases where the terminal block for the motor cannot be attached at the position and dimensions specified for standard models due to where the brake motor is attached. G type models are designed with such cases in mind. Check the dimensions diagram for the position of the terminal block on these G type models.

**Models Equipped with BEW2-2H Brake Rectifiers *Made-to-order Parts**

Option symbol: 2H
These models can be equipped with separate DC switching power supplies (BEW2-2H) for applications requiring a faster response using brake motors used in combination with inverters and other parts.
