RXnC Monitoring The "Monitoring " signal (RYnC) is turned OFF when turning the "Monitor command"
(RYnC) ON specifies a monitored value for monitored values 1 to 6. Turning the "Monitor
command" (RYnC) OFF turns this signal OFF.
RXnD Speed setting
completed (RAM)
This signal is turned ON when turning the "Speed setting command" signal (RYnD) ON
writes a speed command into the inverter's volatile memory (RAM). Turning the "Speed
setting command" signal (RYnD) OFF turns the "Speed setting completed" signal (RXnD)
OFF.
RXnE Not used. -
RXnF Command code
Execution
completed
This signal is turned ON when turning the "Command code execution request" (RYnF) ON
has completed the execution of processing corresponding to command codes 1 to 6. Turning
the "Command code execution request" (RYnF) OFF turns the "Command code execution
completed" signal (RXnF) OFF.
RX(n+1)0
|
RX(n+1)9 Not used. -
RX(n+1)A Alarm status
flag
This signal is turned ON when an inverter alarm (alarm other than er3 ) is generated.
RX(n+1)B Remote station
ready
This signal is turned ON when completing initial data setting places the inverter in the ready
status after the inverter has been powered ON or the hardware has been reset. (This signal is
used for interlocking with reading or writing from/to the master unit.) This signal is turned
OFF concurrently when the "Alarm state flag" (RX(n+1)A) is turned ON if the inverter alarm
is generated.
RX(n+1)C
|
RX(n+1)F Not used. -
n: Value determined by a station address
Note 1: When the condition setting switch of the master unit for "Input data status of data link error station (SW4)" is set to ON,
input data from the data link error station is retained in the status just before the occurrence of the error. Note that this
remains signals, e.g., remote station ready, etc., ON even if an inverter alarm is generated.
Note 2: If an operation command is output from the master when the instruction via communications is disabled (H30=0, 1, or [LE]
instruction OFF), the inverter does not run. However, the input signals "Speed setting completed" and "Command code
execution completed" signal are turned ON. Care must be taken for this. In addition, "I/O check" can be performed on the
keypad to confirm whether input signal is issued from the link (COM), even if the command via communications is
disabled.
