*
1
Calculation for 125% brake torque: (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.).
*
2
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 1000 W and above should maintain the surface temperature below 350°C.
*
4
The calculation of the braking resistor is based on a four-pole motor (1800 rpm). Refer to VFDB series Braking Module
Instruction for more details on the braking resistor.
