* 1 Calculation of 125% braking torque: (kW)*125%*0.8; where 0.8 is the motor efficiency.
Since there is a resistor power consumption limit, the longest operation time for 10% ED is 10 seconds (ON: 10
seconds / OFF: 90 seconds).
* 2 The calculation of the brake resistor is based on a four-pole motor (1800 rpm).
* 3 To dissipate heat, mount a resistors of 400 W or lower to a frame to keep the surface temperature below 250°C
(482°F). Fix a resistor of 1000 W or higher to a surface to keep the surface temperature below 600°C (1112°F).
(If the resistor temperature is higher than 350°C, install extra cooling. If the resistor temperature is higher than
the temperature limit, increase the size of the resistor.)
