While "1" is set in the frequency setting command (RYD), the set frequency (RWw1) is always applied.
*4
If "1" is set in these registers at the same time while Pr. 544 = "0," only one of these is executed.
*5
Torque command can be set for the FR-A700 series only.
*6
Refer to page 37 for operation conditions of inverter reset.
*7
When Pr.544 = "100", RYC to RYF are remotely input available with the programmable controller function. (FR-A700 series
NA/EC version only) For details, refer to the FR-A700 Programmable controller function programming manual.
When "1" is set in the monitor command (RYC), the monitored value is set in the
remote register RWr0, 1, 4 to 7, and "1" is set in the monitoring (RXC). While "1" is
set in the monitor command (RYC), the monitored data is always updated.
When "1" is set in the frequency setting command/torque command (RYD), the set
frequency/torque command (RWw1) is written to RAM of the inverter.
After the writing completes, "1" is set in the frequency setting (torque command)
(RAM)
completion (RXD). Torque command is written to the inverter RAM at the same
time during torque control under Real sensorless vector control or vector control.
When "1" is set in the frequency setting command/torque command (RYE), the set
frequency/torque command (RWw1) is written to RAM and EEPROM of the
inverter. After the writing completes, "1" is set in the frequency setting (torque
command) completion (RXE).
Torque command is written to RAM and EEPROM of the inverter at the same time
during torque control under Real sensorless vector control or vector control.
To change the frequency consecutively, be sure to write data to the inverter RAM.
When "1" is set in the instruction code execution request (RYF), processes
corresponding to the instruction codes set to RWw2, 10, 12, 14, 16 and18 are
executed. "1" is set in the instruction code execution request (RXF) after
completion of instruction codes. When an instruction code execution error occurs,
a value other than "0" is set in the reply code (RWr2, 10, 12, 14, 16, 18).
When "1" is set in the error reset request flag (RY1A) at an inverter fault, the
inverter is reset, then "0" is set in the error status flag (RX1A).
