TPC
[Data type] Bit
TPC The turbo blower constant–power drive control function is:
0 : Disabled.
1 : Enabled.
15801
Maximum in–tube pressure when the turbo blower constant–power drive control
function is enabled
[Data type] Word
[Unit of data] (1=13 Pa)
[Valid data range] 1 to 32767
Maximum in–laser–tube pressure. If the in–laser–tube pressure
calculated from the specified laser power value exceeds the setting of this
parameter, the pressure is clamped to the setting.
15802
Laser power that yields the maximum in–tube pressure when the turbo blower
constant–power drive control function is enabled
[Data type] Word
[Unit of data] W
[Valid data range] 1 to 32767
Laser power that yields the in–laser–tube pressure equal to the setting of
parameter No. 15801. This parameter and parameter No. 15801 are used
to determine the proportional constant for the in–laser–tube gas pressure
and the laser power.
15803
In–tube pressure compensation coefficient when the turbo blower constant–power
drive control function is enabled
[Data type] Word
[Unit of data] 1/1024
[Valid data range] 0 to 32767
Compensation coefficient by which the in–laser–tube pressure is to be
multiplied. A parameter setting of 1024 corresponds to a compensation
coefficient of 1.0.
15804
Maximum open time of the exhaust valve for controlling the in–tube pressure during
oscillation
[Data type] Word
[Unit of data] msec
[Valid data range] 0 to 3000
Specify the maximum open time of the exhaust valve PCV.
