Caution
• If the speed is changed changing and thus, the sign of the command speed during operation, pulse output is started in the
reversed direction after deceleration stop. The waiting time for the pulse output after deceleration stop is "1 ms + scan
time". When the motor cannot be stopped during the waiting time, design a program so that sufficient waiting time is
secured and then the output is restarted after deceleration stop by setting the command speed to 0 once.
• When 0 is set for the command speed at start of the instruction, the operation ends with an error.
