*2. Refer to Chapter 7 “Brake Module and Brake Resistors” in the application manual for “Operation Duration & ED” vs. “Braking
Current”.
*3. To dissipate heat, mount a resistors of 400 W or lower to a frame to keep the surface temperature below 250°C. Fix a resistor of
1000 W or higher to a surface to keep the surface temperature below 350°C. (If the surface temperature is higher than the
temperature limit, install extra cooling or increase the size of the resistor.)
*4. The calculation of the brake resistor is based on a four-pole motor (1800 rpm). Refer to VFDB series Braking Module
Instruction for more details on brake resistor.
