• Phase control gain switching

Code

$B1

$B2

$B3

$B0

COMMAND

CLV phase comparator divisor: 1/2

CLV phase comparator divisor: 1/4

CLV phase comparator divisor: 1/8

No CLV phase comparator divisor used

RES = L

q

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

the phase comparator.

• CLV three-value output

Code

COMMAND

RES = L

$B4

CLV three-value output

$B5

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

q

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.

No. 5502-15/35
