Functions
Reduced Torque Characteristics
Multiplied by the time limit characteristics set in b012/b212/b312 for each frequency.
Constant Torque Characteristics
Do not skip this setting when using a constant torque motor.
Free Setting
To protect the motor according to load, you can freely set the electronic thermal characteristics.
Below is the setting range.
