Calculation for 125% brake toque: (kW)*125%*0.8; where 0.8 is motor efficiency.
Because of the limited resistor power, the longest operation time for 10%ED is 10 seconds (on: 10 sec. / off: 90 sec.).
*

Refer to Chapter 7 “Brake Module and Brake Resistors” in application manual for “Operation Duration & ED” vs. “Braking
Current”.
*
3
For heat dissipation, a resistor of 400 W or lower should be fixed to the frame and maintain the surface temperature below
250°C; a resistor of 1000W and above should maintain the surface temperature below 350°C.
