gefran VDI100 Series

440V: 18.5~22 kW - 100Hz
220V:
22 kW, 440V: 30~160 kW Carrier frequency (11-01) set 8kHz or below 100Hz
220V:
22 kW, 440V: 30~132 kW Carrier frequency (11-01) set 8kHz or higher 80Hz
00-27= 1: Normal Duty Mode
In normal duty mode only applies to control modes V/f and V/f + PG. All other modes must use the Heavy Duty
settings.
Code Parameter Name / Range
00-28 Command characteristic selection of master frequency
0: Positive characteristic (0-10V / 4-20mA = 0 -100%)
1: Negative / inverse characteristic (0-10V / 4~20mA = 100 - 0%)
00-28= 0: Positive reference curve, 0 – 10V / 4 – 20mA = 0 – 100% main frequency reference.
00-28= 1: Negative reference curve, 0 – 10V / 4 – 20mA = 100 – 0% main frequency reference.
Note: Selection applies to analog input AI1 and AI2.
AI2 will be useful for analog input frequency command when 04-05=0.
