NOTE
• The RT signal is the Second function selection signal. The RT signal also enables other second functions. (Refer to
• For the RT signal, set "3" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the function.
• 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 (200/400 V class)
• When the SF-PR motor is selected (Pr.71 = "70 or 73"), 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.
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 (200/400 V class)
• 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.
