Interlocked settings for Voltages Vyknofs1/3/4
For the 9th-generation PDPs, interlocked setting for
Voltages Vyknofs1/3/4 is available on the Factory menu or
with RS232C commands, for easier adjustment. Therefore,
in the adjustment flowchart, the interlocked setting function
is used. (Individual setting for each adjustment value is
NG
also possible, as in the conventional setting methods.

Note:

• The initial value for the interlocked setting value is 128,
including for factory preset values.
• See "[3] DRIVE ASSY" of "5.2 DIAGNOSIS FLOWCHART
OF FAILURE ANALYSIS" for calculation of actually used
voltage values.
