Note!
ƒ
The listed values apply for operation with Lenze servo inverters 9300 or ECS:
– Operation at 400-V mains
– Switching frequency 4 kHz, 8 kHz or 16 kHz.
ƒ
For operation with other servo inverters:
– Do not fall below 4-kHz switching frequency.
– Depending on the modulation and control mode of the servo inverter, the
temperature monitoring may respond. In this case, reduce power!
