When the monitor command (RYC) is switched on, the monitor value is set to
remote resister RWr0, 1, 4 to 7 and monitoring (RXC) switches on. While the
monitor command (RYC) is on, the monitor value is always updated.
When the frequency setting command (RYD) is switched on, the set frequency
(RWw1) is written to RAM of the inverter.
On completion of write, frequency setting completion (RXD) switches on.
When the frequency setting command (RYE) is switched on, the set frequency
(RWw1) is written to RAM and EEPROM of the inverter. On completion of write,
frequency setting completion (RXE) switches on.
To change the running speed consecutively, always write data to the inverter RAM.
When the instruction code execution request (RYF) is switched on, processing
corresponding to the instruction code set to RWw2, 10, 12, 14, 16 and18 is
executed. The instruction code execution completion (RXF) is switched on after
completion of execution of instruction code. When an instruction code execution
error occurs, a value other than "0" is set in the reply code (RWr2,10,12,14,16,18).
If the error reset request flag (RY1A) is switched on only when an inverter fault
occurs, the inverter is reset and the error status flag (RX1A) switches off.
