! 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.
! The setting value for Pr. 12 when using the inverter-dedicated motor (constant-
torque motor).
FR-E520-0.1KND to 7.5KND ............................................................ 4% (Note)
Note: When the Pr. 12 value is as factory-set, changing the Pr. 71 value to the
setting for use of a constant-torque motor changes the Pr. 12 value to 4%
automatically.
Install a mechanical brake. No holding torque is provided.
