User Manual EM303B General Purpose Inverter 0kW ～ 9kW: carrier frequency range 1.000 ～ 16.000 kHz 11kW ～ 37kW: carrier frequency range 1.000 ～ 8.000 kHz 45kW ～ 110kW: carrier frequency range 1.000 ～ 4.000 kHz 132kW ～ 400kW: carrier frequency range 1.000 ～ 3.000 kHz F0-15=0 Automatic torque boost F0-15=1 ～ 10 Fixed torque boost curve F0-15=11 ～ 20 Oil pump motor boost curve F0-15=21 ～ 30 Synchronous motor boost curve F0-15=31 ～ 34 Blower/water pump boost curve F0-15=35 Customer defined V/F curve scaling (Defined via Fd-01 ～ Fd-08) F0-16 Fmax indicates the maximum setting frequency permitted by inverter. Range of Fmax: 20.00 ～ 600.00.
F0-17 Fup indicates the maximum frequency permitted to run after inverter start-up. Range of Fup: Fdown~Fmax. F0-18 Fdown indicates the minimum frequency permitted to run after inverter start-up. Range of Fdown: 0.00Hz~Fup. 1. Upper limit frequency and lower limit frequency should be set prudently as per the actual parameters listed on the nameplate of controlled motor and operational status. Do not make the motor run for a long time in the lower frequency status. Otherwise, the service lifespan of motor will be reduced due to overheating. 2. Correlation of maximum frequency, upper limit frequency, and lower limit frequency: 0.00Hz≤Fdown≤Fup≤Fmax≤600.00Hz 88 No.
