! Use Pr. 10 to set the frequency at which the DC injection brake operation is started.
! Use Pr. 11 to set the period during when the brake is operated.
! Use Pr. 12 to set the percentage of the power supply voltage.
! Change the Pr. 12 setting to 4% when using the inverter-dedicated (constant-torque
motor).
Note: If you leave Pr. 12 as factory-set and change Pr. 71 to the setting for use of the
constant-torque motor, the Pr. 12 setting is automatically changed to 4%.
Install a mechanical brake. No holding torque is provided.
