However, it will still bepossible to use the two arrow keys on the keypad in order to digitally setthe frequency reference value.6.5.6.5 Analog input (AI1/DI4)By default, control terminal 4 will be configured as analog input AI1(0 - +10 V). The corresponding signal common is terminal 0 V.The signal range for this analog input can be configured using P-16:0 = 0 - 10 V (default settings)1 = 0 - 20 mA2 = 4 - 20 mA (t 4 - 20 mA); if there is a wire breakage, the drive will beswitched off and a fault message will be sent3 = 4 - 20 mA (r 4 - 20 mA); if there is a wire breakage, the drive will usethe set ramp time (P-04) to change the frequency to fixed frequency FF1(P-20; default setting = 20 Hz).P-17 can be used to scale analog input AI1’s input signal.ExampleP-01 = 50 Hz, f-REF = 0 - 10 VP-17 = 1.000: (0 - +10 V) x 1 ￫ 0 - 50 HzAt a reference voltage of 10 V, the output frequency will reachthe value in P-01 (100 %).P-17 = 0.100: (0 - +10 V) x 0.1 ￫ 0 - 5 HzAt 10 V, the output frequency will reach a value of 10 % ofP-01.Note:Higher reference voltages (> 10 V) are not permissible!P-17 = 2.000: (0 - +5 (10) V) x 2 ￫ 0 - 50 (50) HzAt 5 V, the output frequency will reach the value in P-01,and will then remain constant within a range > 5 - 10 V(gain factor: 200 %).P-17 = 2.500: (0 - +4 (10) V) x 2.5 ￫ 0 - 50 (50) Hz,At 4 V, the output frequency will reach the value in P-01,and will then remain constant within a range > 4 - 10 V(gain factor: 250 %).
