5.4 Details of Function Codes
5-120
 Discharging capability (F50)
The discharging capability refers to kWs allowable for a single braking cycle, which is obtained based on the
braking time and the motor rated capacity.

When the F50 is set to "0" (For the braking resistor built-in type), no specification of the
discharging capability is required.
 Allowable average loss (F51)
The allowable average loss refers to a tolerance for motor continuous operation, which is obtained based on
the %ED (%) and motor rated capacity (kW).
