Mitsubishi Electric FR-F820-00077 Instruction Manual page 719

Parameters
Setting of operation voltage (torque) (Pr. 12)
● Pr. 12 "DC injection brake operation voltage" will set the percent against the power supply voltage.
● DC injection brake will not operate with setting of Pr. 12 = "0%". (The motor will coast to stop.)
NOTES When the initial value is set in Pr. 12, the setting corresponding to the motor is set according to
the Pr. 71 "Applied motor" setting. (Refer to page 5-301.)
However, when an energy saving motor (SF-HR or SF-HRCA) is used, change the Pr. 12 setting as
shown below.
Inverter
FR-F820-00167(3.7K) or lower
FR-F840-00083(3.7K) or lower
FR-F820-00250(5.5K), FR-F820-00340(7.5K)
FR-F840-00126(5.5K), FR-F840-00170(7.5K)
FR-F820-00490(11K) to FR-F820-00930(22K), FR-F820-01540(37K) or higher
FR-F840-00250(11K) to FR-F840-00470(22K), FR-F840-00770(37K) or higher
FR-F820-01250(30K)
FR-F840-00620(30K)
Even if the setting value of Pr. 12 is made larger, braking torque will be limited so the output cur-
rent will be within the rated current of the inverter.
CAUTION:
E
Install a mechanical brake to make an emergency stop or to stay stopped for a long time.
