NOTE
• The RT signal is the Second function selection signal. The RT signal also enables other second functions. (Refer to
• The RT signal is assigned to terminal RT in the initial status. Set "3" in one of Pr.178 to Pr.189 (Input terminal function
selection) to assign the RT signal to another terminal.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
 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 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.
NOTE
• When selecting the automatic change of torque boost for the SF-PR motor, set Pr.14 Load pattern selection = "0 (initial
value)".
• 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
following table by changing the Pr.71 setting.
