Remarks
Protection
Ground fault
z
Detects overcorrect due to ground fault on inverter
output side to protect inverter. (Detect at starting)
Motor protection
z
Protect general-purpose motor or FUJI inverter
motor with electronic thermal overload.
Input phase failure
protection (only for
3-phase 200V series)
z
The inverter is protected against phase failure on
the input side or over-current due to inter-phase
imbalance.
Stall prevention
z
Controls frequency to prevent OC trip in case of
the output current exceeds the limit value during
acceleration.
z
Lowers the frequency to hold almost constant
torque in case of the output current exceeds the
limit value during constant speed running.
z
Controls frequency to prevent OU trip in case of
the DC link circuit voltage exceeds the limit value
during deceleration.
Retry
z
"Retry" function can be set for the protective func-
tions OC1 to OC3 and OU1 to OU3.
(No. of times of retry: 5, waiting time: 0.5s fixed.)
Dielectric
strength test
z
At 2000Vac for 1 min. between any main circuit
terminals and ground. (10mA or less)
Megger test
z
At 500VDC megger test between any main circuit
terminals and ground (5M
Ω
or more)
Environment
Installation location
z
Indoor use only. Do not install a dusty location
(Degree of pollution: 2) or expose to direct
sunlight, corrosive gases, flammable gases.
Ambient
temperature
z
-10 to +50°C
Ambient
humidity
z
5 to 95% RH (No condensation)
Altitude
