Length reach
In the fixed length control mode, direction cannot be obtained, and only length can
be calculated according the number of pulses. An automatic stop system can be
implemented by feeding the output length reach T/A‑T/B signal from relay to the stop
input terminal of the AC drive.
3.4.18Count Function
A DI terminal is needed to collect the count value (a DI5 terminal must be used in case
of high pulse frequency). Assign the DI terminal with function 25 (counter input).

Value Range Description
Fb‑08 Set count value 1000 1 to 65535
When the count value reaches Fb‑08, the multi‑
functional DO terminal outputs a "set count value

Fb‑09
Designated count
value
1000 1 to 65535
When the count value reaches Fb‑09, the multi‑
functional DO terminal outputs a "designated count
value reach" active signal. Fb‑09 must be lower than
or equal to Fb‑08 (set count value).
As shown in the following figure, a DI terminal is needed to collect the count value.
Assign the DI terminal with function 25 (counter input). When the count value reaches
