• Program example for writing data to EEPROM
as follows:
Frequency setting command Y100D
Y100E
Frequency setting completion X100D
X100E
For EEPROM, write is made only once when Y100E is switched on.
If the set data is changed with Y100E on, it is not reflected on the inverter.
Program example for fault record reading
The following program reads fault records of station 1 inverter to D1.
• Faults history No. 1, No. 2 reading instruction code: H74 (hexadecimal)
For the error codes, refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.
The reply code at the time of instruction code execution is set to D2. (Refer to
Program example for resetting the inverter at inverter error
The following is a program example for resetting station 1 inverter.
NOTE
• The above inverter reset using RY1A may be made only when an inverter error occurs. When
Pr.349 Communication reset
selection
= "0", inverter reset is available independently of the operation mode.
• When using the instruction code execution request (RYF) with the instruction code (HFD) and data (H9696) to reset the
inverter, set a value other than "0" in
Pr.340 Communication startup mode selection
or change the operation mode to the
network operation mode. (For the program example, refer to
• Refer to
for operation conditions of inverter reset.
