NOTE:
*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.)
