Example: Single phase 1x multiplier encoder trigger with no skipping
Note: When the Z-phase input uses a negative logic encoder, set the TRG minimum input time, which is a common measurement
setting, to 7 μs. With negative logic, the Z-phase flag turns ON as shown in the following figure.

Description
The get profile designation information when the operation mode is "high-speed (profile only)"
and batch measurements are off in the get profile command.
byTargetBank

from the inactive surface. See LJV7IF_PROFILE_BANK. (P.9)
byPosMode
Specifies the get profile position specification method. See LJV7IF_PROFILE_POS.
dwGetProfNo
When byPosMode is LJV7IF_PROFILE_POS_SPEC, specifies the profile number for the
profile to get.
byGetProfCnt
The number of profiles to read.
byErase
Specifies whether or not to erase the profile data that was read and the profile data older
than that.
0: Do not erase, 1: erase
