ATT ENT ION : AC drives do not offer protection for externally mounted brake resistors,
especially in the case of brake IGBT failure. A risk of fire exists if external braking
resistors are not protected. External resistor packages must be protected from over
temperature or the protective circuit shown, or equivalent, must be supplied.

Note 1: Always check resistor ohms against minimum resistance for drive being used.
Note 2: Duty cycle listed is based o n full speed to zero speed deceleration.
For constant regen at full speed, duty c ycle capability is half of what is listed.
Application Type 1 represents maximum capability up to 100% braking torque where possible.
Application Type 2 represents more than 100% braking torque where possible, up to a maximum of 150%.
