Explanation
 L
1
: Compensation value for the center of the arc created by the X-axis; L
2
:
Compensation value for the center of the arc created by the Y-axis
 When CNTC is executed, the offset value is automatically written into special
data registers: D1710~D1711 are for the X-axis. D1726~D1727 are for the
Y-axis.
 The compensation value for the center of an arc can be adopted in CW and
CCW.
 If circular movement is executed after the offset value is written into special data
registers, compensation will be carried out in accordance with the offset value.
 Range of parameters: (16-bit) K=-32,768~32,767; H=0~FFFF; D=0~9,999;
(32-bit) KK=-2,147,483,648~2,147,483,647; HH=0~FFFFFFFF; DD=0~9,998
 The 16-bit devices and 32-bit devices can be used together.
