CHV180 series frequency inverter special for elevator Appendix C
.129.
resistor power in the above table is designed on 100% braking torque and 20%
braking usage ratio. If the users need more braking torque, the braking resistor
can decrease properly and the power needs to be magnified.
In the cases where it needs frequent braking (the utilization rate exceeds 20%), it is
necessary to increase the power of the braking resistor according to the situation.
When using the external braking units, please see the instructions of the energy
braking units to set the voltage degree of the braking unit. Incorrect voltage
degree may affect the normal running of the inverter.
