Chapter 8 Built-in High-speed Counter Function
4) Operation when setting Ring Count based on present count value (during decreasing count)
■ If present count value exceeds user-defined range when setting Ring Count
- Error (code no. 27) is occurred and it operates linear counter.
■ If present count value is within user-defined range when setting Ring Count
- Present count value starts to decrease down to the user-defined minimum value and up to
the user-defined maximum value and keeps counting after Borrow occurs.
(1) Based on count value within or out of user-defined range, count will be decided to be within or
out of the range when setting Ring Count.
(2) Ring Count setting when count value is out of the range is regarded as user’s mistake. The
count is not available within the Ring Count range.
(3) Use preset function or the like when using Ring Count so to surely position the count value
within the range.
