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 when using the inverter-dedicated motor (constant-torque
motor).
FR-E520-0.1K to 7.5K-NA, FR-E510W-0.1K to 0.75K-NA........ 4% (Note)
FR-E540-0.4K to 7.5K-NA......................................................... 6%
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.
CAUTION
Install a mechanical brake. No holding torque is provided.
