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 30% ED is 30 seconds (ON: 30
seconds / OFF: 70 seconds).
*
2
The calculation of the brake resistor is based on a four-pole motor (1800 rpm).
*
3
To dissipate heat, mount a resistor 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
