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 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.)

The calculation of the braking current is based on Delta’s brake resistor and default braking voltage (220V
