CXD3068Q

• Input coefficient sign inversion when SFID = 1 and THID = 1

The preset coefficients for the TRK filter are negative for input and positive for output. With this, the

CXD3068Q outputs the servo drives which have the reversed phase to the error inputs..

When SFID = 1, the TRK filter negative input coefficient is applied to the SLD filter, so invert the SLD input

coefficient (K00) sign. (For example, inverting the sign for coefficient K00: E0Hex results in 20Hex.)

For the same reason, when THID = 1, invert the TRK hold input coefficient (K40) sign.
