Some control and monitor signals can be selected and
output from terminals [Y1] to [Y5]. Terminals [Y1] to
[Y4] use transistor output; terminals[Y5A] and [Y5C]
use relay contacts.

"Running" means that the inverter is outputting a
frequency. “RUN” signal is output as when there is output
speed (frequency). When the DC injection brake
function is active, “RUN” signal is off.
See the explanation of function code E30 (frequency
arrival [detection width]).
See the explanation of function codes E31 and E32
(frequency detection).
If the undervoltage protective function activates, i.e.
when 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
while the undervoltage protective function is activating.
Undervoltage detection level: 230V series: 200V, 460V
series: 400V.
This function determines the torque polarity calculated in
the inverter 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.
When the torque limiting activates, the stall prevention
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 during the
current or torque is limited or power regeneration is
prevented.
Following a momentary power failure, this function
reports the start of the 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
when the frequency (before power failure) is recovered.
For 0Hz restart at power recovery, no signal is output
because synchronization ends when power is recovered.
The frequency is not recovered to the frequency before
the power failure occurrence.
Before the motor stops by the 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 effective for motor 1 only.
An ON signal is output when operation command keys
( , and ) on the keypad panel can
be used (i.e., 0 set in "F02 Operation") to issue operation
and stop commands.
This signal is OFF when the function H30(Serial link) is
set to communication side.
