5. HOW TO USE THE PROGRAM
5 - 14
2) Program example 2 (Incorrect usage)
For continuous operations, the acceleration time constant and the deceleration time constant
cannot be changed at each change of the servo motor speed. Therefore, even if you insert an
"STA", "STB", or "STD" command at a speed change, the command is invalid.
