Regenerative Braking Unit and Braking Resistor Combination

Select the combination of the regenerative braking unit(s) and the braking resistor(s) as follows, according 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 Braking Resistor Selection.
• Inverter: Select the model of your inverter. The table below assumes that your inverter is used in the heavy load mode and
                connected to a single motor with the same capacity. Make sure that the approximate braking torque in the table
                shows the assumed value per a motor with the same capacity at ND mode. When using this inverter at LD or VLD
                mode, you need to calculate the torque value by dividing VLD by ND.
• Operating conditions: Show the torque during deceleration and the deceleration time (in % ED) calculated as a percentage
                                  of the cycle time for 1 cycle of operation including the stop time.
• Braking unit/Breaking resistor: Show the required the model and number of units.
• Connection form: Show the configuration of the regenerative braking unit(s) and braking resistor(s) illustrated in the
  connection form table below.
• Restrictions: Show the maximum deceleration time allowable for the combination shown here and the minimum resistance
  that can be connected to the inverter's built-in regenerative braking circuit or external regenerative braking unit(s).
