Permissible brake duty
I am planning to use the inverter to frequently stop a rotational inertial load. What is the definition of the permissible brake duty indicated on the catalog?
Can I use a high-duty brake resistor using a one- or two-rank higher inverter with a 0.2 kW or 0.4 kW motor?
Can I use a high-duty brake resistor using a one- or two-rank higher inverter with a 0.2 kW or 0.4 kW motor?

Answer
When consuming the regenerative power with the brake resistor, the brake transistor is triggered at a certain voltage to make the brake resistor use the regenerative power.
The brake duty is the ON/OFF ratio of this brake transistor.
Since the permissible brake duty depends on the brake resistor, set Pr.70 in accordance with the brake resistor used.
You can use higher-rank inverter capacity and brake resistor (unit).
Note that General-purpose magnetic flux vector control is not available when the two or more higher-rank inverter is used. Use the inverter under V/F control in this case.
