If the undervoltage protective function activates, i.e. when the
DC link circuit 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: 200V DC or less
460V: 400V DC or less
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 being
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 fre-
quency (before power failure) is recovered.
For 0Hz restart at power recovery, no signal is output because
synchronization ends when power is recovered. The fre-
quency 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 OL1 function signal (Mode
select)”, and “E34 OL1 function signal (Level).”
NOTE: This function is effective for motor 1 only.
An ON signal is output when operation command keys (
FWD
,
REV
, and
STOP
keys) on the KEYPAD panel can be used
(i.e., 0 set in “F02 Operation method”) to issue operation and
stop commands.

KEYPAD operation mode [KP] : 8
Overload early warning [OL1] : 7
Torque limiting [TL] : 5
NOTE:
For output signals marked *, refer to instruction manuals for RS-485
communication and the synchronized operation card.
“Running” means that the inverter is outputting a frequency.
“RUN” signal is output when there is output speed (frequency).
When the DC injection brake function is active, this signal is
not output.
See the explanation of function code “E30 FAR function signal
(Hysteresis)”.
