5. Control Input / Output5-115-7 Programmable analog input function (PAI)5-7-1 Types of analog inputsThe VAT2000 includes as standard three analog inputs to terminals FSV, FSI and AUX. Each analoginput can be connected to the internal setting signals shown in Table 5-5 by using the programmableinput function.By connecting an analog interface option (type: U2KV23AD0), the programmable input terminals can beexpanded to up to six channels.Table 5-5 Types of internal setting signals assigned to analog inputSetting range (Note 1)FSV FSI AUX0 - ±10V0 - ±5VSignal name 0-10V0-5V1-5V4-20mA0-20mA1-5VFunction0~100%−100~100%Speed setting 1Speed setting 2Speed setting 30~100%This is the speed setting.The (+) polarity is forward run, and the (-) polarity is thereverse run settings.When the speed setting by analog signal is enabled,then setting 1,2,3 may be selected with the sequenceinput functions (VFS, IFS,AUX).−100~100%Ratio interlockbias setting0~100%0~100%This allows bias setting (C) to ratio interlock functionusing an analog input.0~10V0~5V0~100%(Note 2)Traversecenterfrequencysetting0~100%0~100%This allows center frequency setting for traverseoperation, using an analog input. The positive polarity isthe forward run, and the negative polarity the reverserun.0~10V0~5V0~100%(Note 2)PID feedback 0~100%0~100%This is used for feedback signal to the PID function,using external sensor.Do not use the PID for speed controlDo not use the programmable analog output (FM, AM)as PID’s feedback signal.−300~300%Torque setting 0~300%0~100%This is the analog setting for torque control.The (+) polarity is the forward direction torque, and the(–) polarity is the reverse direction torque. The torquesetting can be limited by using the torque limiterfunction (A11-2, 3).0~10V0~5V0~100%(Note 2)Drive torquelimit reductionsetting0~100%0~100%The drive torque limit (A10-3 or A11-2) may be reducedin percentage using an analog input. For example usinga signal of 0V to +10V the limit torque is reduced from 0to 100%This function is enabled when LIM1, is ON.0~10V0~5V0~100%(Note 2)Regenerativetorque limitreductionsetting0~100%0~100%The regenerative torque limit (A10-4 or A11-3) may bereduced in percentage using an analog input.This function is enabled when LIM2 is ON.−300~300%0~300%Torque bias 1setting0~300%0~300%A torque bias signal during either speed or torquecontrol is allowed using an analog input.This is enabled when the torque bias function TRQB1,is ON..(Note 1) FSV, FSI, AUX inputs and modes are selected with C12-0 to 2.(Note 2) AUX: The setting is limited to 0% during the −10 to 0V and −5 to 0V input.
