Resistance; Allowable Continuous Power; Allowable Braking Duty Factor - Panasonic AMK3000P22 Installation Manual

· Precautions on selection of braking resistor by customer himself/herself
1) Resistance (Ω)
The resistance shown in the reference table during the resistor selection can be
increased properly, but it will cause the braking torque reduced accordingly.
2) Allowable continuous power (W)
The allowable power shown in the reference table can be increased properly, but the
higher power can make the resistor generate a lot of heat (300℃ ). Please consult with
resistor manufacture, and provide protection during installation.

3) Allowable braking duty factor (%)

The higher the allowable continuous power for braking resistor is, the higher duty
factor can be used theoretically. But the internal resistor of inverter will overheat,
therefore please use duty factor of 5% shown in the reference table.
1) Braking torque: 100% min.
2) Maximum working time: T1max = 5s
3) Maximum duty factor: T1/T0 (%ED) = 5%
