circuit
F
Input
The motor rotates in forward direction if F and
CC are connected, while it slows down to a stop
if this Connection is broken. ( ST and CC are
connected).
R
Input
The motor rotates in reverse direction if R and
CC are connected, while it slows down to a stop
if this connection is broken. (ST and CC are
connected ).
ST
Input
The motor is on standby if ST and CC are
connected. It coasts to a stop (free-run stop) if
this connection is broken. This terminal can be
used for interlocking.
RES
Input
This inverter protective function is disabled if
RES are CC is connected. Shorting RES and
CC has no effect when the inverter is in a
normal condition.
S1
Input
The motor rotates at a preset speed if S1 and
CC are connected.
S2
Input
The motor rotates at a preset speed if S2 and
CC are connected.
S3
Input
The motor rotates at a preset speed if S3 and
CC are connected.
S4
Input
*
The motor rotates at a preset speed if S4 and
CC are connected.
