5-23Drive running (RUN)Value 0: The RUN signal is output when there is outputspeed (drive is outputting a frequency). When the DCinjection brake function is active, the RUN signal is off.Frequency arrival (FAR)Value 1: See the explanation for function code E30(frequency arrival [detection width]).Frequency detection (FDT1)Value 2: See the explanation for function codes E31 andE32 (frequency detection).Stopping due to undervoltage (LV)Value 3: If the undervoltage protective function activates,i.e. if the main circuit DC voltage falls below theundervoltage detection level, an ON signal is output. Thesignal goes off when the voltage recovers and increasesabove the detection level. The ON signal is retained aslong as the undervoltage protective function is active.Undervoltage detection level: 230V series: 200V460V series: 400VTorque polarity detection (B/D)Value 4: This function determines the torque polaritycalculated in the drive and outputs a signal indicatingdriving or braking torque. An OFF signal is output fordriving torque; an ON signal is output for braking torque.Torque limiting (TL)Value 5: When torque limiting is active, the stall preven-tion function is automatically activated to change theoutput frequency. The torque limiting signal is output tolighten the load and also used to display overloadconditions on the monitor device. This ON signal isoutput while the current or torque is limited or powerregeneration is prevented.Restart after momentary power failure (IPF)Value 6: Following a momentary power failure, thisfunction reports the start of restart mode, the occurrenceof an automatic pull-in, and the completion of therecovery operation.Following a momentary power failure, an ON signal isoutput when power is recovered and a synchronization(pull-in) operation is performed. The signal goes off aftera frequency level equal to that prior to power failure hasbeen recovered.For 0 Hz restart at power recovery, no signal is outputbecause synchronization ends when power is recovered.The frequency is not recovered to the level before thepower failure occurred.Overload early warning (OL1)Value 7: Before the motor is stopped by a trip operationof an electronic thermal O/L relay, this function outputsan ON signal when the load reaches the overload earlywarning level.Either the electronic thermal O/L relay early warning oroutput current overload early warning can be selected.For setting procedure, see E33 Overload early warning(operation selection) and E34 Overload early warning(operation level).Note: This function is only effective for Motor 1.Keypad panel operationValue 8: An ON signal is output when the operationcommand keys (FWD, REV and STOP) on the keypadpanel can be used (i.e., F02 Operation = 0) to issueoperation and stop commands.Drive stopping (STOP)Value 9: This function outputs an inverted signal to RUNto indicate zero speed. An ON signal is output when theDC injection brake function is operating.Ready for operation (RDY)Value 10: This function outputs an ON signal when thedrive is ready to operate. The drive is ready to operateafter the main circuit and control circuit power have beenestablished where the drive protective function is notactivated.About one second is required from power-on to ready foroperation under normal conditions.Switching between the AC line and the drive(SW88)(SW52-2)(SW52-1)Value 11, 12, 13: To perform a transfer between the lineand the drive, the relay sequence can be accomplishedusing values 11, 12 and 13 on the “Y” outputs. Thesevalues will provide outputs that can be used for openingand closing contactors in the transfer sequence. For adetailed explanation of these outputs please refer to thefactory.Motor 2 switching (SWM2)Value 14: When a signal for switching to Motor 2 is inputfrom the terminal selected by Terminals X1 to X9, thisfunction selects and outputs the signal to switch themagnetic contactor for the motor. Since this switchingsignal is not output during running, including when the DCinjection braking function is operating, a signal must be re-input after output stops.Terminal AX function (AX)Value 15: When an operation command (FWD or REV) isentered, this function outputs an ON signal. When a stopcommand is entered, the signal goes off after drive outputstops. When a coast-to-stop command is entered, andthe drive protective function is operating, the signal goesoff immediately.Pattern operation stage change (TU)Value 16: When the pattern operation stage changes, thisfunction outputs a one-shot, 100ms ON signal to report astage change.
