Environment specification
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.
