APPLICATIONS OF Σ-SERIES PRODUCTS3.2.10 Using the Reference Pulse Inhibit Function (INHIBIT)1003.2.10 Using the Reference Pulse Inhibit Function (INHIBIT)For position control only.1) OutlineThis function inhibits a position control from counting input reference pulses.While this function is being used, the motor remains in servo locked (clamped) status.The P-CON signal is used to enable or prohibit this function.When this function is used, therefore, the P-CON signal cannot be used to switch be-tween proportion (P) control and proportional/integral (PI) control for speed loop. (PI con-trol is always used.)ServopackReference pulseCn-01 bit FErrorcounterFeedback pulseSchematic Block Diagram for INHIBIT FunctionP-CON2) How to Use Reference Pulse Inhibit Function: INHIBITTo use the INHIBIT function, set the following memory switch to 1:Cn-01 Bit F Reference Pulse InhibitFunction (INHIBIT)FactorySetting: 0For Position Control OnlyEnables the INHIBIT function.Setting Meaning0 Does not use the INHIBIT function.Reference pulses are always counted.Uses the INHIBIT function.P-CON signal is used to enable or prohibit the INHIBIT function.P-CON MeaningOFF Counts reference pulses.1ONProhibits the Servopack from counting referencepulses.The motor remains in servo locked (clamped)status.3Positions
