Dc Injection Brake (Pr. 10 To Pr. 12) - Mitsubishi Electric FR-E520 Instruction Manual

4.2.7

DC injection brake (Pr. 10 to Pr. 12)

Pr. 10 "DC injection brake operation frequency"
Pr. 11 "DC injection brake operation time"
Pr. 12 "DC injection brake voltage"
By setting the DC injection brake voltage (torque), operation time and operation starting
frequency, the stopping accuracy of positioning operation, etc. or the timing of operating
the DC injection brake to stop the motor can be adjusted according to the load.

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