Explanations:
1. ABST enables absolute coordinate system. Absolute coordinate is the coordinate starting from “0.” When the
target position P(I) > current position (DD1848, DD1928, DD2008), the motor will conduct forward running.
When the target position P(I) < current position, the motor will conduct reverse running.
2. INCT enables relative coordinate system. Relative coordinate is the relative displacement moved from current
position (DD1848, DD1928, DD2008). When the relative coordinate is a positive value, the motor will conduct
forward running. When the relative coordinate is a negative value, the motor will conduct reverse running.
3. Even if absolute coordinate system is adopted, the distance to center of arc (I/J), the arc radius (R), and the
additional distance set by SINTR and DINTR instructions are all regarded as relative displacement.
Program Example:
When DVP-PM switches from MANU to AUTO without designating coordinate system, the default setting for the
program will be absolute coordinate system (ABST). After INCT instruction is executed, the motion instructions
starting from the next row (e.g. DRV, LIN, CW, CCW) will be operated in relative coordinate system as below.
