Ambient Temperature
CT (Heavy Duty) load: - 10 ~ 50℃
VT (Normal Duty) load: - 10~ 40℃
(It is recommended that you use less than 80% load when you use VT load at 50℃.
And if ambient temperature is above 40℃, Carrier frequency should be lower than
default value.)
Storage temperature
-20~60℃
Ambient humidity
Below 90% RH (Installed with no dew condensation)
Vibration
5.9m/s
2
(0.6G). 10~55Hz
Shock
10 Hz to 20Hz, 9.8m/s² Max, 20Hz to 55Hz, 5.9m/s² Max
Location
Under 1000m above sea level, indoors
(Installed away from corrosive gasses dust)
Standard Compliant
UL 508C, IEC 61800-3
Protective Design
IP00 open-chassis, NEMA Type 1 enclosure.
Option
Fieldbus, Ext I/O, Encoder, Remote operator, Bracket, AC reactor,
Noise filter, Braking resistor, Dynamic braking unit
(EMC filter and DC reactor are Built in.)
Note 1)
'98.01'(Motor control mode)
to 2 (sensorless vector control) Selected, refer to below
Set a value
more than 2kHz at
'98.03'(PWM carrier frequency)
Sensorless vector performance will be reduced when using a motor less than
half of the rated capacity of the VFD.
Multiple motors cannot be driven by sensorless vector control.
Note 2) To operate the motor over rated frequency, consult the motor manufacturer about
the maximum allowable rotation speed.
