Chapter 7 Optional Accessories MS300 460V three-phase Table 7-1-4 575V three-phase Table 7-1-5 *1 Calculation for 125% brake torque: (kW)*125%*0.8; where 0.8 is motor efficiency. Because of the limited resistor power, the longest operation time for 10% ED is 10 seconds (ON: 10 sec. / OFF: 90 sec.). *2 The calculation of the brake resistor is based on a four-pole motor (1800 rpm). *3 For heat dissipation , a resistors of 400 W or lower should be fixed to the frame and maintain the surface temperature below 250°C; a resistor of 1000 W and above should maintain 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.) 7-3 Applicable *1 125% Braking Torque / 10% ED Max.
