Goodrive10 Series Mini VFD Technical data

Appendix A Technical data
A.1 Derating in application
A.1.1 Capacity
Choose a VFD 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:
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.
The rated capacity is the capacity at the ambient temperature of 40°C.
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.
A.1.2 Derating
If the ambient temperature on the site where the VFD is installed exceeds 40°C, the altitude
exceeds 1000m, or the carrier frequency is changed from 4 kHz to 8, 12 or 15 kHz, the VFD
needs to be derated.
A.1.2.1 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.

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.
