Revolution or pitch counting circuit

In order to enable the digital angle of the external data line to be input from the DB1-DB16 of the converter
, the DA LO AD terminal (pin 32) must be used to make it logical. ,
load the data on the data line into the counter . For this purpose, set the ENABLE terminal (pin 26) to logic
1 in advance. Make DB1-DB16 in a high-impedance state, then change to logic 0, allowing the data to be latched.
    Similarly, the AD 2S82A can also be used as a solid-state control transformer.
    (3) External spindle rotation number or pitch number counter; in actual application, it is necessary to
count the number of rotations of the resolver and the number of pitches of the induction synchronizer. This requirement can be achieved by using an external counter and
some gate circuits (see Figure 8 1 6). In Figure 8 16, the RC (RIP-
PI,E CI.OCK) and DIR (DIRECTK)N) signals come from RDC.
