• Phase control gain switching

The phase control gain can be changed by changing the divisor used by the dividers in the stage immediately preceding

the phase comparator.

Code

COMMAND

RES = L

$B1

CLV phase comparator divisor: 1/2

$B2

CLV phase comparator divisor: 1/4

$B3

CLV phase comparator divisor: 1/8

$B0

No CLV phase comparator divisor used

• CLV three-value output

The CLV three-value output command allows the CLV to be controlled by a single pin. However, the spindle gain is 6

dB lower when this pin is used, so applications must increase the gain in the servo system.

Code

COMMAND

RES = L

$B4

CLV three-value output

$B5

CLV two-value output (the scheme used by previous products)
