Basic specifications

Processing

• By turning on i_bEN (Execution command), the count value is calculated from the angle (input in increments of 0.1

degrees). The value to be calculated is the one when the resolution is set as the ring counter upper limit value and 0 is set

as the ring counter lower limit value.

• The calculation formula for o_dCountVal (count value) is as follows: i_uAngle  (3600  i_udResolution) + i_uZeroValue.

When a calculation value is greater than i_udResolution (Resolution), the i_udResolution (Resolution) value is subtracted

from the calculation value and the result is stored in o_dCountVal (Count value).
