12 Examples of Programs
12.3 Programs for Forward/Reverse Rotation (Step Ladder (STL) Program)
B - 160
*1. If the initial values (maximum speed, acceleration/deceleration time, zero return speed, creep speed)
can be used, it is not necessary to create the program.
→ For the related devices, refer to Section 4.1 to Section 4.4.
*2. The maximum transfer distance for each jogging operation is ±999,999 pulses (pulse output range of
FNC158 (DRVI) instruction). To move the workpiece further, execute the JOG command again.
