Signal names are initial values. Using Pr. 180 to Pr. 183, you can change input signal functions. Refer to page 163 for details of Pr. 180 to Pr. 183.
∗2
The signal is not changeable.
∗3
No signal is assigned in the initial setting. Using Pr. 184, you can change the assigned input signal. Refer to page 163 for the details of Pr. 184.
∗4
While "1" is set in the frequency setting command (RYD), the set frequency (RWw1) is always applied.
∗5
If "1" is set in these registers at the same time while Pr. 544 = "0," only one of these is executed.
∗6
Refer to page 110 for operation conditions of inverter reset.

OFF: Stop command
ON: Reverse rotation

Turning ON the signal activates the function assigned to Pr. 182.
1
Turning ON the signal activates the function assigned to Pr. 181.
1
Turning ON the signal activates the function assigned to Pr. 180.

ON: Second function is selected
2
Turning ON the signal activates the function assigned to Pr. 183.
1
Turning ON the signal activates the function assigned to Pr. 184.
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 (RYD), the set frequency (RWw1)
is written to RAM of the inverter.
After the writing completes, "1" is set in the frequency setting completion (RXD).
When "1" is set in the frequency setting command (RYE), the set frequency (RWw1)
is written to RAM and EEPROM of the inverter. After the writing completes, "1" is set
in the frequency setting completion (RXE).
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 and 18 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).
When "1" is set, a start command is input to the inverter.
start When "1" is set in RY0 and RY1, a stop command is input.
