Chapter 5 — ConfigurationBulletin No. 50006-519-01B7 →General Configuration Menu December 1996Table 33: Analog Input Port RangesAnalog Input Port Input RangeAI10 to 10 VAI20 to 20 mA; 4 to 20 mAAI3 -10 V to 10 V [1]AI40 to 20 mA; 4 to 20 mA[1] AI3 acts as an absolute value when used for PI Regulator.NOTE: The analog inputs (shaded) are available only when an I/O extension moduleis present.Next, calculate the system gain and offset values. System gain and offset aredetermined by the setpoint minimum and maximum process values and thefeedback minimum and maximum process values. Use the following formulas tocalculate system gain and offset, and then enter the values into the drive controllerwith the SP GAIN and OFFSET entries on the SET POINT menu.SP GAIN=⎛ Setpoint Max. – Setpoint Min.------------------------------------------------------------------------------------- ⎞×9999⎝Feedback Max. – Feedback Min. ⎠OFFSET=⎛ Setpoint Min. – Feedback Min.------------------------------------------------------------------------------------- ⎞×9999⎝Feedback Max. – Feedback Min. ⎠Setpoint Min. Process value corresponding to the minimum setpoint signal. Setpoint Min.may either be the maximum process level or the minimum process level,depending on the type of application. Controller will run at low speed atsetpoint minimum.Setpoint Max. Process value corresponding to the maximum setpoint signal. SetpointMax. may either be the maximum process level or the minimum processlevel, depending on the type of application. Controller will run at high speedat setpoint maximum.Feedback Min. Process value at which feedback is minimum.Feedback Max. Process value at which feedback is maximum.9999 Process resolution factor. 9999 corresponds to 99.99%.FeedbackFEED BACKFB INPUT : AI2MIN FEED BACK: +0MAX FEED BACK: +1000LOW LEVEL ALM: +0†, & ENT to selectHIGH LEVEL ALM: +090 © 1996 Square D All Rights Reservedηττπ://νιχοντρολσ.χοm
