ECO REFERENCE MANUAL
On all FS6 575V inverters and all FS7, FS8 & FS9 MIDIMASTER Eco inverters, the
switching frequency can only be either 2kHz or 4kHz (with the exception of the 315kW unit
where the switching frequency is fixed at 2 kHz).
The switching frequency will automatically be reduced if the inverter internal protection
detects an excessive heat sink temperature. The switching frequency will automatically be
returned to the setting once this temperature returns to normal.

Description / Notes
0 = Multi-motor mode
4 = Energy saving mode see section 6
Sets additional current during ramping to
ensure consistent starting and to overcome
stiction effects
If efficiency is shown on the motor rating
] plate, calculate the power factor as follows:
pf =
1.732 x efficiency x nom. volts x nom. amps
If neither power factor nor efficiency are
shown on the motor rating plate
- set P080 = 0.
