FR-D700 SC EC

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 SF-JRCA:
FR-D720S-100SC or less, FR-D740-080SC or less ............. 4%
FR-D740-120SC or more ...................................................... 2%
Energy saving motor SF-HR, SF-HRCA:
FR-D720S-100SC or less, FR-D740-080SC or less .............. 4%
FR-D740-120SC or more ....................................................... 3%
NOTES
For the FR-D740-120SC and 160SC, 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, 23, 40, 43) to the value selecting the constant
torque motor (1, 13, 50, 53).
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, 50, 53) to the value selecting the
standard motor (0, 3, 23, 40, 43).
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.
