• When parameter settings are converted from FR-A500 inverters to FR-A800 (CA type) inverters, set the following
parameters as required in the "Parameter list" window because they are not converted.
Pr.54 FM/CA terminal function selection
Pr.291 Pulse train I/O selection
Pr.869 Current output filter
C8 (Pr.930) to C11 (Pr.931) (Terminal CA calibration parameters)
• It is recommended to adjust the setting of the following parameters again after conversion according to the mechanical
system because they are used for adjustment.
Pr.0 Torque boost
Pr.12 DC injection brake operation voltage
C2 (Pr.902) to C7 (Pr.905) (Frequency setting input calibration parameters)
• Since the communication-related parameters (Pr.117 to Pr.124, Pr.331 to Pr.337, and Pr.341) are also converted,
communication may be disabled depending on the setting after the setting is written to parameters. For example, when
Pr.122/Pr.336 RS-485 communication check time interval = "0 (initial value)", a communication error (E.PUE, E.SER)
occurs immediately after the operation mode with the command source is selected.
• Note the following when Advanced magnetic flux vector control or vector control is selected (Pr.80 Motor capacity is not
"9999", Pr.81 Number of motor poles is not "9999").
Tuning and parameter setting of the target inverter are recommended, if offline auto tuning is performed (Pr.71 Applied
motor = "3, 4, 7, 8, 13, 14, 17, 18, 23, 24") or motor constants is directly input (Pr.71 = "5, 6, 15, 16") at the source inverter.
When an SF-HR or SF-HRCA motor is used, set Pr.71 = "40, 43, 44, 50, 53, or 54" after writing the converted parameter
to the target inverter. (Conversion of Pr.82, Pr.85, Pr.86, Pr.89, Pr.90 to Pr.94 is not necessary)
• The following wiring needs to be changed. Refer to the FR-A800 series Instruction Manual for details of wiring.
When using pulse train input of the FR-A5AP, change the connection to JOG/pulse train input terminal of the inverter (JOG
terminal is changed to pulse train input by Convert). Note that a resistance is necessary when connecting.
When using a relay output terminal of the FR-A5NR, change the connection to terminal ABC2 of the inverter.
When stop position command of orientation control was given from the FR-A5AX (Pr.360 = "1") and Pr.369 Number of
encoder pulses was "2048" or "4096", wire to the FR-A8AX as shown below.
Pr.369 Number of encoder pulses = "2048"
Change connection from X0 to X1......from X11 to X12 (X0 is always open)
Pr.369 Number of encoder pulses = "4096"
Change connection from X0 to X2......from X11 to X13 (X0 and X1 are always open)
• There is a change in the following functions. Refer to the FR-A800 series manual for details.
When automatic restart after instantaneous power failure is performed with residual voltage detection system by TSEN50
(Pr.162 = "11"), it is changed to automatic restart after instantaneous power failure with reduced voltage system. Fully
check that there is no problem in automatic restart operation after instantaneous power failure. If there are any problem,
consider changing to f search system, etc.
Y29 (acceleration speed detection) signal is deleted, and major fault by E.OS occurs instead.
When stop position command of orientation control was given from the FR-A5AX (Pr. 360 = "1"), orientation with Pr.369
Number of encoder pulses "1025 to 2047", or "2049 to 4059" is not supported by Convert.
Since convert is performed using the full scale value of the motor torque as 200%, the full scale value of the load meter is
converted as 200% (FR-A500 (L) series is 100%). Use Pr.866 to change. In such a case, note that the full scale value of
the motor torque also changes accordingly.
