Motor brake and stop operation Parameter
6 - 102
Operation voltage (torque) setting (Pr. 12)
Use Pr. 12 to set the percentage to the power supply voltage.
When Pr. 12 = 0%, the DC injection brake is not operated. (At a stop, the motor coasts.)
When using the constant-torque motor (SF-JRCA) and energy saving motor (SF-HR, SF-HRCA), change
the Pr. 12 setting as follows:
Constant-torque motor:
FR-E720S-110SC or less, FR-E740-095SC or less ......................4%
FR-E740-120SC or more ....................................................................2%
Energy saving motor SF-HR, SF-HRCA:
FR-E720S-110SC or less, FR-E740-095SC or less .......................4%
FR-E740-120SC and 170SC ...............................................................3%
FR-E740-230SC and 300SC ...............................................................2%
NOTES For the FR-E740-120SC and 170SC, when the Pr. 12 setting is the following, changing the Pr. 71
"Applied motor" setting automatically changes the Pr. 12 setting. Therefore, it is not necessary to
change the Pr. 12 setting.
Parameter 12 = 4% (initial value)
The Pr. 12 setting is automatically changed to 2% if the Pr. 71 value is changed from the value
selecting the standard motor (0, 3 to 6, 23, 24, 40, 43, 44) to the value selecting the constant torque
motor (1, 13 to 16, 50, 53, 54).
Parameter 12 = 2%
The Pr. 12 setting is automatically changed to 4% (initial value) if the Pr. 71 value is changed from
the value selecting the constant torque motor (1, 13 to 16, 50, 53, 54) to the value selecting the
standard motor (0, 3 to 6, 23, 24, 40, 43, 44).
Even if the Pr. 12 setting is increased, braking torque is limited so that the output current is within
the rated inverter current.
As stop holding torque is not produced, install a mechanical brake.
