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 .
