INVT IPE300 Series User Manual

IPE300 series engineering VFD Technical data
-335-
B.2.2.2 Derating due to altitude
It is recommended to use the VFD at an altitude not higher than 1000m. When the altitude exceeds
1000m, derate by 1% for every increase of 100m. When the altitude exceeds 3000m, consult the local
INVT dealer or office for details.
B.2.2.3 Derating due to carrier frequency
The VFDs in different power classes are different in carrier frequency. The rated power of a VFD is
defined based on the carrier frequency set in factory. If the carrier frequency exceeds the factory
setting, the power of the VFD is derated by 10% for each increased 1 kHz.
B.3 Grid specifications
Grid voltage
AC 3PH 380V(-15%)–440V(+10%)
AC 3PH 520V(-15%)–690V(+10%)
Short-circuit
capacity
According to the definition in IEC 60439-1, the maximum allowable short-circuit
current at the incoming end is 100 kA. Therefore, the VFD is applicable to
scenarios where the transmitted current in the circuit is no larger than 100 kA
when the VFD runs at the maximum rated voltage.
Frequency
50/60Hz±5%, with a maximum change rate of 20%/s
B.4 Motor connection data
Motor type
Asynchronous induction motor or permanent-magnet synchronous motor
Voltage
