12AC30 series General Purpose I/O OptionAnalogue Inputs (7004-01-00 only)The 7004-01-00 offers three identical analogue input ports on terminalX21.Terminal Name Range DescriptionX2101 AN 0V 0V Analogue signal reference02 ANIN11 -10V to +10V Analogue input 11(default = unassigned)03 ANIN12 -10V to +10V Analogue input 12(default = unassigned)04 ANIN13 -10V to +10V Analogue input 13(default = unassigned)Notes: These analogue input ports are differential. That means that thesignal reference on terminal X21/01 is not directly connectedinternally to the drive’s 0V terminal. It is allowed to float relativeto the drive’s 0V, within the limits of the common mode voltagerange (see specification on page 13). This effectively eliminatesground loops.Therefore X21/01 must be connected to the user’s 0V signalreference which should be grounded at an appropriate point inthe system. See the example application on page 14. If any analogue inputs ANIN11 to ANIN13 are unused, theyshould be connected to X21/01 (AN 0V) to prevent invalidvalues being reported. |
