Inverter stopping [STOP]
This function outputs an inverted signal to Running (RUN) to indicate zero speed. An ON signal is output when the DC injection brake function is operating.
Ready output [RDY]
This function outputs an ON signal when the inverter is ready to operate. The inverter is ready to operate when the main circuit and control circuit power is established and the inverter protective function is not activating. About one second is required from
Line/Inv changeover [SW88] [SW52-2] [SW52-1]
To perform switching operation between the line and the inverter, the sequence prepared in the inverter can be used to select and output signals for opening and closing the magnetic contactors connected to the inverter. As the operation is complex, refer to technical documentation for the FRENIC5000G11S series when using this function.
As the sequence will operate automatically when SW88 or
Motor 2 /Motor 1 [SWM2]
When a signal for switching to motor 2 is input from the terminal selected by terminals [X1] to [X9], this function selects and outputs the signal for switching the magnetic contactor for the motor. As this switching signal is not output during running including when the DC injection braking function is operating, a signal must be
Auxiliary terminal [AX]
When an operation (forward or reverse) command is entered, this function outputs an ON signal. When a stop command is entered, the signal goes off after inverter output stops. When a
Time-up signal for pattern operation [TU]
When the pattern operation stage changes, this function outputs a
Cycle completion signal for pattern operation [TO]
When the seven stages of a pattern operation are completed, this function outputs a
Stage No. indication for pattern operation [STG1] [STG2] [STG4]
During pattern operation, this function reports the stage (operation process) being operated.

In normal operation terminals do not output a signal.
Fan operation signal [FAN]
When used with "H06 Cooling fan ON/OFF control," this function outputs a signal while the cooling fan is operating.
Auto-resetting [TRY]
When a value of 1 or larger is set to "H04 Retry operating," the signal is output while retry operation is activating when the inverter protective function is activated.
Universal DO [U-DO]
Assigning value "27" to a transistor output terminal renders the terminal a universal DO terminal.
This function enables ON/OFF through the
This function serves only to turn on and off the transistor output through communication and is not related to inverter operation.
Overheat early warning [OH]
This function outputs a early warning signal when heat sink temperature is (overheat detection level - 10℃) or higher.
Life expectancy detection signal [LIFE]
When either of data for the Life expectancy judgment of the function code:U09 to U11 reaches at the Life expectancy judgment level, the ON signal is output. However, the inverter does not do alarm.
Moreover, the alarm output for any fault (30A, 30B, 30C ) does not operate.
