Phase Compensation Type (Valid with SVA-01 version 1.01 or later)
Select a setting method for Phase Correct Setting (OL28).
0: Incremental value add method (default)
1: Absolute value set method
This bit is valid when the electronic cam function is enabled (setting: OW05, bit 1 = 1).
If using an electronic shaft (OW05, bit 1 = 0), the incremental value of Phase Correct Setting (OL28),
which is the difference between the values from the previous H scan and the current H scan, is added to the tar-
get position regardless of the setting of this bit.
 Precautions if using as an electronic cam (OW05, bit 1 = 1)
• If Absolute value 1 is selected for the Phase Compensation Type when using an electronic cam, always take
measures to prevent a sudden and extreme change in the target position before executing the move com-
mand. For example, set the Phase Correct Setting (OL28) to the same value as CPOS for 32 bit (DPOS)
(IL14). If preventive measures are not taken, the axis may abruptly move, resulting in a serious situa-
tion.
• If using the electronic cam function, do not change the setting of this bit while the move command is being
executed. Although the setting of this bit can be changed at any time, changing the setting while the move
command is being executed may move the axis abruptly, resulting in serious situation.
 Precautions if using as an electronic shaft (OW05, bit 1 = 0)
• The setting method of Phase Correct Setting (OL28) for the SVA-01 Module and that for the SVB/SVB-
01 Modules are different. For the SVA-01 Module, the set value of Phase Correct Setting (OL28) is sim-
ply added to the target position.
