12-4 Regenerative Braking Unit and Braking
Resistor Combination Selection Table
A table that lists the available combinations of the inverter with the regenerative braking unit and brak-
ing resistor is provided on the next page.
Below is the meaning of each header item of this combination table. Choose the combination appropri-
ate to your inverter.
If the usage rate exceeds 10% ED, or if you need a torque larger than the approximate braking torque,
you need to follow the instruction provided in
A-5 Overview of Inverter Selection on page A-12.
Item Description
Inverter Select the model of your inverter.
However, the table below assumes that your inverter is used in the heavy
load mode and connected to a single motor with the same capacity.
Therefore, in the light load mode, a motor with the same capacity means a
motor that is one size larger in capacity than the inverter and the approxi-
mate braking torque decreases in proportion to the motor capacity.
Operating condition Shows the torque during deceleration (Approximate braking torque) and
the processing time for regeneration such as deceleration time calculated
as a percentage of the cycle time for 1 cycle of operation including the
stop time (% ED).
Braking unit/Braking resistor Shows the required model and number of units.
Connection form Shows the configuration of the regenerative braking unit(s) and braking
resistor(s) that are illustrated in the connection form table after this selec-
tion table.
Restriction Shows the processing time for regeneration, such as the maximum decel-
eration time, allowable for the combination shown in the combination
selection table (Allowable continuous ON time) and the minimum resis-
tance that can be connected to the inverter’s built-in regenerative braking
circuit or external regenerative braking unit(s) (Min. connection resis-
tance).
