Operation functions
Maximum/minimum frequency setting, frequency jump operation,
external thermal relay input selection, automatic restart operation after
instantaneous power failure, forward/reverse rotation prevention, slip
compensation, operation mode selection, offline auto tuning function,
PID control, computer link operation (RS-485)
Operating status
2 open collector output signals can be selected from inverter running,
up to frequency, frequency detection, overload alarm, zero current
detection, output current detection, PID upper limit, PID lower limit, PID
forward/reverse rotation, operation ready, minor fault and alarm, and 1
contact output (230VAC 0.3A, 30VDC 0.3A) can be selected.
Control specifications
Output signals
For meter
1 signal can be selected from output frequency, output current and
output voltage. Pulse train output (1440 pulses/s/full scale).
Operating
status
Output voltage, output current, set frequency, running.
Control panel

Alarm
definition
Alarm definition is displayed when protective function is activated. 4
alarm definitions are stored.
Display
LED display Power application (POWER), Alarm (ALARM)
Protective/alarm functions
Overcurrent shut-off (during acceleration, deceleration, constant
speed), regenerative overvoltage shut-off, undervoltage (Note 1),
instantaneous power failure (Note 1), overload shut-off (electronic
overcurrent protection), brake transistor alarm, output short circuit, stall
prevention, brake resistor overheat protection, fin overheat, fan failure
(Note 4), parameter error, PU disconnection, output phase failure
protection, ground fault over current protection (400V class), starting-
time ground fault overcurrent protection (other than 400V class) .

Environment
Altitude, vibration
Maximum 1000m (3280.80 feet) above sea level for standard
operation.
After that derate by 3% for every extra 500m (1640.40 feet) up to
2500m (8202.00 feet) (91%).

or less (conforming to JIS C 0911)
Note:1. When undervolta
e or instantaneous power failure has occurred, alarm
displa
or alarm output is not provided but the inverter itself is protected.
Overcurrent, re
enerative overvolta
e or other protection ma
be activated
at power restoration according to the operating status (load size, etc.)
2. Temperature applicable for a short period in transit, etc.
3. The brakin
torque indicated is a short-duration avera
e torque
which
varies with motor loss
when the motor alone is decelerated from 60Hz in
the shortest time and is not a continuous re
enerative torque. When the
motor is decelerated from the frequenc
hi
her than the base frequenc
,
the avera
e deceleration torque will reduce. Since the inverter does not
contain a brake resistor, use the optional brake resistor when re
enerative
ener
is lar
e.
The optional brake resistor cannot be used with 0.1K and
0.2K.) A brake unit (BU) may also be used.
4. Not provided for the FR-E540-0.4K, 0.75K-NA, FR-E520-0.1K to 0.4K-NA
and FR-E510W-0.1K to 0.75K-NA which are not equipped with a coolin
fan.
