Note: 1. When undervoltage or instantaneous power failure has occurred, alarm
display or alarm output is not provided but the inverter itself is protected.
Overcurrent, regenerative overvoltage or other protection may 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 braking torque indicated is a short-duration average torque (which
varies with motor loss) when the motor alone is decelerated from 60Hz in
the shortest time and is not a continuous regenerative torque. When the
motor is decelerated from the frequency higher than the base frequency,
the average deceleration torque will reduce. Since the inverter does not
contain a brake resistor, use the optional brake resistor when regenerative
energy is large. (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 cooling
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)
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.
1 signal can be selected from output frequency, motor current and
output voltage. Pulse train output (1440 pulses/second/full scale).
Output voltage, output current, set frequency, running.
Alarm definition is displayed when protective function is activated. 4
alarm definitions are stored.
