Mitsubishi Electric FR-F800 Series Instruction Manual page 403

NOTE
• The Y39 signal remains ON after the motor is stopped as long as the second flux remains.
• The X28 signal is disabled while the Y39 signal is ON.
• The STF and STR signals are enabled after completing tuning at start.
• The Inverter running (RUN) signal is not turned ON during online auto tuning. The RUN signal is turned ON after starting up.
• The setting is invalid under V/F control or PM motor control.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) or Pr.190 to Pr.196 (Output
terminal function selection) may affect the other functions. Set parameters after confirming the function of each terminal.
 Tuning the second motor (Pr.574)
• When one inverter switches the operation between two different motors, set the second motor in Pr.450 Second applied
motor. (In the initial setting, no second motor is applied. (Refer to
• Perform tuning using Pr.574 Second motor online auto tuning.
• Pr.574 is enabled when the Second function selection (RT) signal is turned ON.

*1 If a motor with substantially low rated current compared with the inverter rated current is used, speed and torque accuracies may deteriorate due
to torque ripples, etc. Set the rated motor current to about 40% or higher of the inverter rated current.
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.
