Altivar 16 AC Drive Dynamic braking Dynamic braking Dynamic braking allows the Altivar 16 to function in quadrants 2 and 4 of the speed/torque curve and dissipates excess braking energy in an external resistor. Applications : machines with high inertia, overhauling loads and machines with fast cycles. The braking module is integrated in the Altivar 16 except for ATV16U09M2 and ATV16U18M2.

Slip compensation is disabled when the motor is regenerating. 1.50 C/Cn For demanding applications (overhauling loads, hoisting) it is necessary to calculate the value of the resistor. Consult your local sales office. The minimum resistance value is 50 Ω (no matter what the rating of the Altivar 16). Description : The braking resistor kit contains two 50 Ω type PX1 resistors and is supplied with a 1A fuse which is a Gould Shawmut TRSIR.
The kit does not include an enclosure. 8 1 2
