Parameters
Automatic change of torque boost for the SF-PR motor
● When the SF-PR motor is selected (Pr. 71 = "70, 73, or 74"), the Pr. 0 "Torque boost" setting is
automatically changed to enable output of the 6 Hz 150% torque under V/F control by setting
Pr. 81 "Number of motor poles" according to the number of the SF-PR motor poles.
NOTES When using the automatic change of torque boost for the SF-PR motor, set Pr. 14 "Load pattern
selection" = "0".
When the Pr. 0 setting is changed from its initial value, the automatic change is not performed.
Automatic change of Pr. 0 "Torque boost" and Pr. 12 "DC injection brake operation voltage"
When initial values are set in Pr. 0 and Pr. 12, the Pr. 0 and Pr. 12 settings are automatically changed to
the values in the table below by changing the Pr. 71 setting.
