DVP-ES3 Series Programming Manual If the minimum value of the deadband in S 1 is larger than the maximum value of the deadband in S 2 , the instruction is not executed. 2. Only the 32-bit instructions can use the 32-bit counter, but not the device E. 3. The following graphs show how this instruction uses the deadband. BAND is executed. BAND is not executed. Output value Output value The lower limit value of the deadband Input value Input value The upper limit value of the deadband 4. The minimum value of the deadband in S 1 , the maximum value of the deadband in S 2 , the input value in S 3 , and the output value in D must be within the range described below. 5.
For the BAND instruction, the minimum value of the deadband in S 1 , the maximum value of the deadband in S 2 , the input value in S 3 , and the output value in D must be between -32768 to 32767. Suppose the minimum value of the _6 deadband in S 1 is 10 and the maximum value of the deadband in S 3 is -32768. The instruction calculates the output value in D as follows. Output value in D = -32768-10=16#8000-16#000A=16#7FF6=32758 6. For the DBAND instruction, the minimum value of the deadband in S 1 , the maximum value of the deadband in S 2 , the input value in S 3 , and the output value in D must be between -2147483648 to 2147483647.
Suppose the minimum value of the deadband in ( S 1 +1, S 1 ) is 1000 and the maximum value of the deadband in ( S 3 +1, S 3 ) is -2147483648. The instruction calculates the output value in ( D +1, D ) as follows. Output value in ( D +1, D) =-2147483648-1000=16#80000000-16#000003E8=16#7FFFFC18 =2147482648 6-386
