3.2  Digital Outputs
3.2.1  Y1, Y2, Y3 Digital Outputs
Y1 can be used as alarm output, motion status output or general purpose output.
Y2 can be used as brake output, motion status output or general purpose output.
Y3 cab be used as tach-out, timing signal output(50pulse/rev), motion status output or general
purpose output.
Please use STF Congurator software for Y1,Y2 and Y3 function conguration. 
Following graphs shows some common connection methods for the outputs: 
NOTE: Do not connect the outputs to more than 30VDC power supply. And the current of 
each output terminal must not exceed 100mA.
