Technical data Appendix A
A.1 What this chapter contains
This chapter contains the technical specifications of the inverter, as well as provisions for fulfilling the
requirements for CE and other marks.
A.2 Ratings
A.2.1 Capacity
Inverter sizing is based on the rated motor current and power. To achieve the rated motor power given
in the table, the rated current of the inverter must be higher than or equal to the rated motor current.
Also the rated power of the inverter must be higher than or equal to the rated motor power.
Note:
1. The maximum allowed motor shaft power is limited to 1.5·PN. If the limit is exceeded, motor
torque and current are automatically restricted. The function protects the input bridge of the
drive against overload.
2. The ratings apply at ambient temperature of 40°C
3. It is important to check that in common DC systems the power flowing through the common
DC connection does not exceed PN.
A.2.2 Derating
The load capacity decreases if the installation site ambient temperature exceeds 40°C, the altitude
exceeds 1000m or the switching frequency is changed from 4kHz to 8, 12 or 15kHz.
A.2.2.1 Temperature derating
In the temperature range +40°C~+50°C, the rated output current decrease by 1% for every additional
1°C. Refer to the below list for the actual derating.
Note: Do not use the inverter when the temperature is above 50°C, otherwise, our company
will not be responsible for any consequences.
