CMM-PN02 Operation Manual
Below is the STEP 7 program-editing screen and an example of writing a program by using 20xx
message format.
1. PIW282 means 2103H (output frequency).
2. PQW276 means 2000H (control word).
3. The writing of the program explains as follows.
OB1 Program (Main Loop) is explained as follows:
a. Judging if PIW282 (2103H) equals to 6000. If YES, PQW276 (2000H) equals to 1,
which means the drive stops running; if NO, go to RES label;
b. Judging if PIW282 (2103H) equals to 0. If YES, PQW276 (2000H) equals to 2,
which means the drive starts running; if NO, go to END label;
Therefore, the drive performs continuous actions of running until stop, and then starts running
again.
