Application Cross-Reference

Note 1: Always check resistor ohms against minimum resistance for drive being used.

Note 2: Duty cycle listed is based on full speed to zero speed deceleration.

For constant regen at full speed, duty cycle 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%.

ATTENTION: 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 3: For 11 and 15 kW (15 and 20 HP) normal duty external resistor applications, use two

7.5 kW (10 HP) size resistors wired in parallel.
