*1. A, AN, B, BN, Z, and ZN terminals.
*2. DA, DB, DZ, IO1, IO2, and IO3 terminals.
*3. The angular error expresses the variation from the ideal phase difference of interpolation outputs DA and DB as a phase difference of the input period.
Converting 3° and expressing as a percentage of the output period gives 13.3% using equation (1) below.
