(3) 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 disabled. (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.
SF-JRCA: 00083 or less ...4%, 00126 to 01160...2%
SF-HR, SF-HRCA: 00083 or less...4%, 00126 and 00170...3%, 00250 to 01160...2% (00620...1.5%)
REMARKS
 For the 00126 and 00170, when the Pr. 12 setting is as below, changing the Pr. 71 Applied motor setting changes the Pr. 12
setting automatically, it is not necessary to change the Pr. 12 setting.
(a) When Pr. 12 is 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, 2) to the value selecting the constant motor (1).
(b) When Pr. 12 is 2%
The Pr. 12 setting is automatically changed to 4% if the Pr. 71 value is changed from the value selecting the constant motor
(1) to the value selecting the standard motor (0, 2).
 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.
