| When the monitor command (RYC) is switched on, the monitored value is set to remote | |
RYC | Monitor command | register RWr0 and monitoring (RXC) switches on. While the monitor command (RYC) is | |
|
| on, the monitored value is always updated. | |
RYD | Frequency setting | When the frequency setting command (RYD) is switched on, the set frequency (RWW1) | |
is written to the inverter. (Note 3) | |||
(Note 4) | command (RAM) | ||
On completion of write, frequency setting completion (RXD) switches on. | |||
|

RYE | Frequency setting | When the frequency setting command (RYE) is switched on, the set frequency (RWW1) | |
is written to the inverter. | |||
(Note 4) | command (E2PROM) | ||
On completion of write, frequency setting completion (RXE) switches on. | |||
|

|
| When the instruction code execution request (RYF) is switched on, processing | |
RYF | Instruction code execution | corresponding to the instruction code set to RWW2 is executed. After completion of | |
instruction code execution, instruction code execution completion (RXF) switches on. | |||
