B.2.2.3 Derating due to carrier frequency
The inverters in different power classes are different in carrier frequency. The rated power of a
inverter is defined based on the carrier frequency set in factory. If the carrier frequency exceeds the
factory setting, the power of the inverter is derated by 10% for each increased 1 kHz.
B.3 Grid specifications
AC 3PH 380V (-15%)–440V (+10%)
AC 3PH 520V (-15%)–690V (+10%)
According to the definition in IEC 60439-1, the maximum allowable
short-circuit current at the incoming end is 100 kA. Therefore, the
inverter is applicable to scenarios where the transmitted current in
the circuit is no larger than 100 kA when the inverter runs at the
maximum rated voltage.
50/60 Hz±5%, with a maximum change rate of 20%/s
B.4 Motor connection data
Asynchronous induction motor or permanent-magnet synchronous
motor
0–U1 (Motor rated voltage), 3PH symmetrical, Umax (inverter
rated voltage) at the field-weakening point
The short-circuit protection for the motor output meets the
requirements of IEC 61800-5-1.
1.5 times the motor rated power
B.4.1 EMC compatibility and motor cable length
The following table describes the maximum motor cable lengths that meet the requirements of the EU
EMC directive (2014/30/EU).
All models (with external EMC filters)
Maximum motor cable length (m)
You can learn the maximum length of the motor cable through the running parameters of the inverter.
To understand the accurate maximum cable length for using an external EMC filter, contact the local
IMO office.
For description about the environments category II (C3), see section B.6 EMC regulations.
