IPE300 series engineering VFD Technical data
-334-
Appendix B Technical data
B.1 What this chapter contains
This chapter describes the technical data of the VFD and its compliance to CE and other quality
certification systems.
B.2 Derated application
B.2.1 Capacity
Choose a VFD model based on the rated current and power of the motor. To endure the rated power
of the motor, the rated output current of the VFD must be larger or equal to the rated current of the
motor. The rated power of the VFD must be higher or equal to that of the motor.
Note:
1. The maximum allowable shaft power of the motor is limited to 1.5 times the rated power of the
motor. If the limit is exceeded, the VFD automatically restricts the torque and current of the motor.
This function effectively protects the input shaft against overload.
2. The rated capacity is the capacity at the ambient temperature of 40°C.
3. You need to check and ensure that the power flowing through the common DC connection in the
common DC system does not exceed the rated power of the motor.
B.2.2 Derating
If the ambient temperatue on the site where the inverter is installed exceeds 40°C, the altitude
exceeds 1000 m, or the carrier frequency is changed from 4 kHz to 8, 12, or 15 kHz, the VFD needs
to be derated.
B.2.2.1 Derating due to temperature
When the temperature ranges from +40°C to +50°C, the rated output current is derated by 1% for
each increased 1 °C. For the actual derating, see the following figure.
Derating coefficient (%)

Note: It is not recommended to use the VFD at an environment with the temperature higher than
50°C. If you do, you shall be held accountable for the consequences caused.
