* 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 30% ED is 30 seconds (ON: 30
seconds / OFF: 70 seconds).
2
* The calculation of the brake resistor is based on a four-pol
e 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.)
*4 The calculation of the braking current is based on Delta's brake resistor and default braking voltage (220V
380V ; 440V : 760V
