Braking Unit,

Braking Resistor Unit

To supply braking for inverter, a

braking unit and braking resistor unit

are needed. 0.4 to 15 kW (200 V/400 V)

inverters are equipped with braking

units as standard. Connect inverter-

mounted or separately-installed type

units according to inverter

applications and output.

＊1 When connecting a mounting type resistor or braking resistor

unit, set system constant L3-04 to 0 (stall prevention disabled

during deceleration). If operating without changing the

constant, motor does not stop at set deceleration time.

＊2 When connecting mounting type braking resistor, set system

constant L8-01 to 1 (braking resistor protection enabled).

＊3 Load factor during deceleration to stop a load with constant torque. With constant output

or continuous regenerative braking, the load factor is smaller than the specified value.

＊4 Resistance value per one braking unit. Select a resistance value that is larger than

connectable minimum resistance value to obtain enough braking torque.

＊5

For an application with large regenerative power such as hoisting, the braking torque or

other items may exceed the capacity of a braking unit with a braking resistor in a standard

combination (and result in capacity overload). Contact your YASKAWA representatives

when the braking torque or any other item exceeds the values in the table.
