Motor brake and stop operation
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-HR-CA), change the Pr. 12 setting as follows:
SF-JRCA:
SF-HR, SF-HRCA: 00083 or less ... 4%, 00126, 00170 ... 3%,
NOTES 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:
Parameter 12 = 4% (initial value)
The Pr. 12 setting is automatically changed to 2% if the Pr. 71 value is changed to from the
value selecting the standard motor (0, 2) to the value selecting the constant motor (1).
Parameter 12 = 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).
As stop holding torque is not produced, install a mechanical brake.
