Control Circuit Terminal Block - Toshiba TOSVERT VF-AS1 Instruction Manual

2.3.2 Control circuit terminal block

The control circuit terminal block is common to all equipment.
(VFAS1-*****-WN,HN)
Color of a label is yellow.
⇒ How to set input terminal function, refer to section 7.
Terminal Input/ Function (Sink logic)
symbol output VFAS1-****-WN, HN
Shorting across F-CC causes forward
rotation; open causes deceleration
F Input
stop. (Across PWR-P24/PLC is short
state.)
Shorting across R-CC causes reverse
rotation; open causes deceleration
R Input
stop. (Across PWR-P24/PLC is short
state.)
Shorting and then opening RES-CC
cancels the status held by an inverter
protective function. When the inverter
RES Input
is operating normally, shorting and
then opening RES-CC produces no
effect.
Shorting across S1-CC causes preset
S1 Input
speed operation.
Shorting across S2-CC causes preset
S2 Input
speed operation.
Shorting across S3-CC causes preset
S3 Input
speed operation.
SW3: When SW3 is in the S4 position,
RR/S4 Input S4 and CC are shorted and preset
speed operation is selected.

Function (Source logic)
Shorting across F-P24/PLC causes
forward rotation; open causes
deceleration stop.
Shorting across R-P24/PLC causes
reverse rotation; open causes
deceleration stop.
Shorting and then opening RES-
P24/PLC cancels the status held by an
inverter protective function. When the
inverter is operating normally, shorting
and then opening RES-P24/PLC
produces no effect.
Shorting across S1-P24/PLC causes
preset speed operation.
Shorting across S2-P24/PLC causes
preset speed operation.
Shorting across S3-P24/PLC causes
preset speed operation.
SW3: When SW3 is in the S4 position,
S4 and P24/PLC are shorted and preset
speed operation is selected.

is used (in sink logic
mode, i.e., when
SINK (PLC) is
selected), connect the
