Testing the Start and Stop of the Drive
To verify if the host controller can control the drive through CMM-PN02
, you must write the PLC
program.
For STEP 7, the program-editing screen below illustrates an example of writing
a program by
using 60xx message format.
1. PIW260 means 6102H (actual output frequency).
2. PQW256 means 6000H (control word).
3. The writing of the program explains as follows.
OB1 Program (Main Loop) is explained as follows:
a. Judging if PIW260 (6102H) equals to 6000. If YES, PQW256 (6000H) equals to 128
(0x80), which means the drive stops running; if NO, go to RES label;
b. Judging if PIW260 (6102H) equals to 0. If YES, PQW256 (6000H) equals to 129 (0x81);
if NO, go to END label;
Therefore, the drive performs continuous actions of running until stop, and then starts running
again.
