DeviceNet operation.
Control specifications
Output signals
Operating status
1 contact output (230VAC 0.3A, 30VDC 0.3A) can be selected from
inverter running, up to frequency, frequency detection, overload alarm,
zero current detection, output current detection, operation ready, minor
fault and alarm.
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.

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, starting-time ground fault

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

Note:1. When undervolta

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
g
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
g
enerative torque. When the
motor is decelerated from the frequenc

hi
g
her than the base frequenc
y
,
the avera
g
e deceleration torque will reduce. Since the inverter does not
contain a brake resistor, use the optional brake resistor when re

(
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-E520-0.1KND to 0.4KND which are not equipped
with a cooling fan.
