Please see Table 11-1 for selecting braking resistor for EM303B. Table 11-1 Braking Resistor Selection Remarks: 1. See User Manual of BR100 Braking Unit for selecting braking resistor for EM303B-018~400. 2. Cables listed in above table refer to the lead cable of single resistor.
The DC bus should be uprated if the resistors are in parallel connection. 3. Cable should withstand voltage≥AC450V, temperature resistance :105 ℃ . 4. Because there is a resistor limit of power consumption, the longest operation time for 10%ED is 10S (On: 10S/ Off:90S). 173 130 238 210 Output Frequ Run Emergency Sto Acceleration Deceleration Inverter Model No.
