(2) PLS/SIGN
Input the pulse signal for counting the increased/decreased pulse in the
pulse input (PLS). Input the signal for controlling forward run and reverse
run in the direction sign (SIGN).
1) "[Pr.22] Input signal logic selection" is positive logic
• The motor will forward run when the direction sign is HIGH.
• The motor will reverse run when the direction sign is LOW.
2) "[Pr.22] Input signal logic selection" is negative logic
• The motor will forward run when the direction sign is LOW.
• The motor will reverse run when the direction sign is HIGH.
