2 Functions of Devices in DVP-PLC M0, M1 = On refers to drawing a 90° arc in Quadrant I; M0, M2 = On refers to drawing a 90° arc in Quadrant II; M0, M3 = On refers to drawing a 90° arc in Quadrant III; M0, M4 = On refers to drawing a 90° arc in Quadrant IV.

Program explanation: When the direction control pin is On, the direction will be a positive one; otherwise, it will be a negative one (see Figure 9).
When X0 = On, D0 will accumulate once and the 2 axes will draw a 90° arc. Output frequency and number of pulses: see Table 2.
