Mitsubishi Electronics FR-E5NC 5.1.2 Input signals (inverter (FR-E5NC) → master unit)

COMMUNICATION SPECIFICATIONS

5.1.2 Input signals (inverter (FR-E5NC) → master unit)

The input signals to the master unit are indicated. (Output signals from inverter)

Device	Signal	Description
No.
RX0	Forward running	OFF : Other than forward running (during stop or reverse rotation)
		ON : Forward running
RX1	Reverse running	OFF : Other than reverse running (during stop or forward rotation)
		ON : Reverse running
RX2	Running (RUN)	On while the inverter is running. (Note)
RX3	Up to frequency (SU)	Switched on when the output frequency reaches the set frequency ± Pr. 41.
RX4	Overload (OL)	Switched on when stall prevention is activated and switched off when stall prevention is
		deactivated.
RX5	Reserved	Reserved for the system.
RX6	Frequency detection (FU)	Switched on when the output frequency reaches set frequency. (Note)
RX7	Alarm (A, B, C)	Switched on when the inverter's protective function is activated to stop the output. (Note)
RX8
RX9	Reserved	Reserved for the system.
RXA
RXB
RXC	Monitoring	Switched on when the monitored value is set to RWr0 by the monitor command (RYC)
		switching on. Switched off when the monitor command (RYC) is switched off.
RXD	Frequency setting command	Switched on when the set frequency is written to the inverter by the frequency setting
	(RAM)	command (RYD) switching on. Switched off when the frequency setting command
		(RYD) is switched off.
RXE	Frequency setting command	Switched on when the set frequency is written to the inverter by the frequency setting
	(E2PROM)	command (RYE) switching on. Switched off when the frequency setting command
		(RYE) is switched off.
	Instruction code execution	Switched on on completion of the processing corresponding to the instruction code
RXF		(RWW2) which is executed when the instruction code execution request (RYF) switches
	completion
		on. Switched off when the instruction code execution completion (RXF) is switched off.
