• Gain and bias If F01 = 3 (the sum of [12] + [C1] is enabled), the bias and gain are independently applied to each of the voltage and current inputs given to terminals [12] and [C1], and the sum of the two values is applied as the reference frequency. In the case of unipolar input (terminal [12] with C35 = 1, terminal [C1], terminal [V2] with C45 = 1) As shown in the graph above, the relationship between the analog input and the reference frequency specified by frequency command 1 can arbitrarily be determined by points "A" and "B." Point "A" is defined by the combination of the bias (F18) and its base point (C50); Point "B," by the combination of the gain (C32, C37 or C42) and its base point (C34, C39 or C44). The combination of C32 and C34 applies to terminal [12], that of C37 and C39, to [C1] (C1 function), and that of C42 and C44, to [C1] (V2 function). Configure the bias (F18) and gain (C32, C37 or C42), assuming the maximum frequency as 100%, and the bias base point (C50) and gain base point (C34, C39 or C44), assuming the full scale (10 VDC or 20 mA DC) of analog input as 100%. • The analog input less than the bias base point (C50) is limited by the bias value (F18). • Specifying that the data of the bias base point (C50) is equal to or greater than that of each gain base point (C34, C39 or C44) will be interpreted as invalid, so the inverter will reset the reference frequency to 0 Hz. Example: Setting the bias, gain and their base points when the reference frequency 0 to 60 Hz follows the analog input of 1 to 5 VDC to terminal [12] (in frequency command 1). (Point A) To set the reference frequency to 0 Hz for an analog input being at 1 V, set the bias to 0% (F18 = 0). Since 1 V is the bias base point and it is equal to 10% of 10 V (full scale of terminal [12]), set the bias base point to 10% (C50 = 10). (Point B) To make the maximum frequency equal to the reference frequency for an analog input being at 5 V, set the gain to 100% (C32 = 100). Since 5 V is the gain base point and it is equal to 50% of 10 V (full scale of terminal [12]), set the gain base point to 50% (C34 = 50). 4-29
In the case of bipolar input (terminal [12] with C35 = 0, terminal [V2] with C45 = 0) Setting C35 and C45 data to "0" enables terminal [12] and [V2] to be used for bipolar input (-10 V to +10 V) respectively. When both F18 (Bias) and C50 (Bias base point) are set to "0," the negative and positive voltage inputs produce reference frequencies symmetric about the origin point as shown below. Configuring F18 (Bias) and C50 (Bias base point) to specify an arbitrary value (Points A1, A2, and A3) gives the bias as shown above. A reference frequency can be specified not only with the frequency (Hz) but also with other menu items, depending on the setting of function code E48 (= 3 to 5, or 7). [ 3 ] Using digital input signals UP/DOWN (F01 = 7) When the UP/DOWN control is selected for frequency setting with a run command ON, turning the terminal command UP or DOWN ON causes the output frequency to increase or decrease, respectively, within the range from 0 Hz to the maximum frequency as listed below. To enable the UP/DOWN control for frequency setting, it is necessary to set F01 data to "7" and assign the UP and DOWN commands to any of digital input terminals [X1] to [X7], [FWD] and [REV] with any of E01 to E07 (data = 17 or 18). UP DOWN Data = 17 Data = 18 Function OFF OFF Keep the current output frequency. ON OFF Increase the output frequency with the acceleration time currently specified. OFF ON Decrease the output frequency with the deceleration time currently specified. ON ON Keep the current output frequency. 4-30
