P4.21,P4.22 are the complement to function 12,13 listed in Table 6-6.
Set counts given: It refers to when how many pulse signals input from Xi (count trigger signal
input function terminal), OC (2-way open collector output terminal) or relay outputs an index
signal.
When Xi inputs the 8th pulse signal, OC outputs an index signal, that is P4.21=8, shown as
Fig.6-27.
Specified counts given: It refers to when how many pulse signals input from Xi, OC or relay
outputs an index signal, until set counts arrival.
When Xi inputs the 5th pulse signal, relay outputs an index signal, until set counts 8 arrival,
that is P4.22=5, shown as Fig.6-27. When specified counts bigger than set counts, specified
counts invalid.

If output current exceeds continuously current detection level set by P4.23 (the actual
detection level current = P4.23 X inverter rated current), after the delay time set by P4.24, the
open collector outputs valid signal shown as Fig. 6-28 (refer to P4.11).
