§4-17. Servo Status Changes Produced by the LOCK Signal
When the LOCK signal becomes low, the TRK servo assumes the gain-up status and the SLD servo turns off
in order to prevent SLD free-running.
Setting D6 (LKSW) of $38 to 1 deactivates this function.
In other words, neither the TRK servo nor the SLD servo change even when the LOCK signal becomes low.
This enables microcomputer control.
§4-18. Description of Commands and Data Sets
The following description contains portions which convert internal voltages into the values when they are
output externally and describe them as input conversion or output conversion.
Input conversion converts these voltages into the voltages entering input pins before A/D conversion.
Output conversion converts PWM output values into analog voltage values.
Both types of conversion are calculated at V
= 5.0V. If this voltage changes, the conversion values also
DD
change proportionally. (Voltage conversion = V
/5; V
: used supply voltage)
