NOTE
• To change the running frequency continuously from a programmable controller, check that the frequency setting complete (for
example, X1021) turns ON, and the reply code from the intelligent register is H0000. Then change the setting data (for
example, W100) continuously.
• To write the running frequency to the EEPROM, change the following points in the program shown above.
- Frequency setting command (from Y1021 to Y1022)
- Frequency setting completion (from X1021 to X1022)
<Timing chart for writing to the RAM>
*1 To the EEPROM, a writing is performed only once after the command Y1022 turns ON.
*2 If the set data is changed at the command Y1022 ON, the change is not applied to the inverter.
 Programming example for the fault record reading
The following program reads the fault records of the station 1 inverter to output to D1.
• Faults history No. 1 and 2 reading instruction code: H74 (hexadecimal)
