Calculation for 125% brake toque: (kw)*125%*0.8; where 0.8 is motor efficiency.
Because there is a resistor limit of power consumption, the longest operation time for 10%ED is 10sec (on: 10sec/ off:
90sec).
2
*
Please refer to the Brake Performance Curve for "Operation Duration & ED" vs. "Braking Current".
3
*
For heat dissipation, a resistor of 400W or lower should be fixed to the frame and maintain the surface temperature below
50℃; a resistor of 1000W and above should maintain the surface temperature below 350 .
NOTE
1.
Definition for Brake Usage ED%
Explanation: The definition of the brake usage ED (%) is for assurance of enough time for the brake unit and brake resistor
to dissipate away heat generated by braking. When the brake resistor heats up, the resistance would increase with
temperature, and brake torque would decrease accordingly. Recommended cycle time is one minute.
