Chapter 7 Optional Accessories CFP2000 The optional accessories listed in this chapter are available upon request. Installing additional accessories to your drive would substantially improve the drive’s performance. Please select an applicable accessory according to your need or contact the local distributor for suggestion. 7-1 Brake Resistors and Brake Units Used in AC Motor Drives Table 7-1 * 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 Refer to Chapter 7 “Brake Module and Brake Resistors” in application manual for “Operation Duration & ED” vs. “Braking Current”. * 3 For heat dissipation, a resistor 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. * 4 The calculation of the braking resistor is based on a four-pole motor (1800 rpm). Refer to VFDB series Braking Module Instruction for more details on the braking resistor. NOTE 1. Specification and Appearances of Brake Resistors 1-1 Wire wound resistors:
For 1000W and above, refer to the following appearance of wire wound resistor (Figure 7-1) and its model and specification comparison table (Table 7-2) for details.
