5-23
Drive running (RUN)
Value 0: The RUN signal is output when there is output
speed (drive is outputting a frequency). When the DC
injection 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 and
E32 (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 the
undervoltage detection level, an ON signal is output. The
signal goes off when the voltage recovers and increases
above the detection level. The ON signal is retained as
long as the undervoltage protective function is active.
Undervoltage detection level: 230V series: 200V
460V series: 400V
Torque polarity detection (B/D)
Value 4: This function determines the torque polarity
calculated in the drive and outputs a signal indicating
driving or braking torque. An OFF signal is output for
driving 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 the
output frequency. The torque limiting signal is output to
lighten the load and also used to display overload
conditions on the monitor device. This ON signal is
output while the current or torque is limited or power
regeneration is prevented.
Restart after momentary power failure (IPF)
Value 6: Following a momentary power failure, this
function reports the start of restart mode, the occurrence
of an automatic pull-in, and the completion of the
recovery operation.
Following a momentary power failure, an ON signal is
output when power is recovered and a synchronization
(pull-in) operation is performed. The signal goes off after
a frequency level equal to that prior to power failure has
been recovered.
For 0 Hz restart at power recovery, no signal is output
because synchronization ends when power is recovered.
The frequency is not recovered to the level before the
power failure occurred.
Overload early warning (OL1)
Value 7: Before the motor is stopped by a trip operation
of an electronic thermal O/L relay, this function outputs
an ON signal when the load reaches the overload early
warning level.
Either the electronic thermal O/L relay early warning or
output 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 operation
Value 8: An ON signal is output when the operation
command keys (FWD, REV and STOP) on the keypad
panel can be used (i.e., F02 Operation = 0) to issue
operation and stop commands.
Drive stopping (STOP)
Value 9: This function outputs an inverted signal to RUN
to indicate zero speed. An ON signal is output when the
DC injection brake function is operating.
Ready for operation (RDY)
Value 10: This function outputs an ON signal when the
drive is ready to operate. The drive is ready to operate
after the main circuit and control circuit power have been
established where the drive protective function is not
activated.
About one second is required from power-on to ready for
operation 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 line
and the drive, the relay sequence can be accomplished
using values 11, 12 and 13 on the “Y” outputs. These
values will provide outputs that can be used for opening
and closing contactors in the transfer sequence. For a
detailed explanation of these outputs please refer to the
factory.
Motor 2 switching (SWM2)
Value 14: 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 to switch the
magnetic contactor for the motor. Since this switching
signal is not output during running, including when the DC
injection 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) is
entered, this function outputs an ON signal. When a stop
command is entered, the signal goes off after drive output
stops. When a coast-to-stop command is entered, and
the drive protective function is operating, the signal goes
off immediately.
Pattern operation stage change (TU)
Value 16: When the pattern operation stage changes, this
function outputs a one-shot, 100ms ON signal to report a
stage change.
