In the following figure, the actual length is a monitored value. Actual length (Fb-06) = Number of pulses
sampled by DI/Number of pulses per meter (Fb-07). When the actual length (Fb-06) exceeds the
reference length (Fb-05), the relay or DO terminal (function 31) outputs the "length reach" ON signal.
During fixed length control, length reset can be implemented by a multi-function DI terminal (function
30). For details, see the following figure.
Assign length reset to DIx
Assign length reach to DO/RO
F4-01/05/07/09/11/13/15 = 30
F5-01/03/05/07/09 = 31

Length reach
Only length can be calculated according to the number of pulses but the rotation direction cannot be
identified in fixed length control mode. An automatic stop system can be implemented by connecting
the output length reach T/A-T/B signal of the relay to the stop input terminal.
4.4.15 Counting Function
If the count values need to be collected by DI terminals, assign function 27 (counter input) to the DI
terminal.
Para. No. Name
Default
Value Range Description
Fb-08 Reference count value
1000 1 to 65535
When the count value reaches Fb-08, the DO
terminal outputs an active signal indicating
that the reference count value is reached.
Fb-09
Designated count value
1000 1 to 65535
When the count value reaches Fb-09, the DO
terminal outputs an active signal indicating
that the designated count value is reached. Fb-
09 must be less than or equal to Fb-08
(reference count value).
