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.
Color of a label is yellow.
 How to set input terminal function, refer to section 7.
Note：Control circuit terminal block is different between the previous version of CPU（Up to Ver.124） and the
present version of CPU（above Ver.130）.If it was changed into different type, Inverter doesn't work correctly.
When you change a control circuit terminal block, please be careful whether the type of terminal is the same.
Previous version: There is "ST" terminal instead of "PWR" terminal and color of a terminal label is white.
Present version: There is "PWR" terminal instead of "ST" terminal and color of a terminal label is yellow.
Terminal Input/ Function (Sink logic)
symbol output VFAS1-****-WN1
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.

VFAS1-****-WP1
Shorting across F-P24/PLC causes
forward rotation; open causes
deceleration stop. (Across
PWR-P24/PLC is short state.)
Shorting across R-P24/PLC causes
reverse rotation; open causes
deceleration stop. (Across
PWR-P24/PLC is short state.)
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.

24Vdc-5mA or less
Lan current signal.
Choose low current
contacts to avoid
poor attaching.
*Sink/source selectable

Sink input
ON:Less than DC10V
OFF:DC16V or more
Source input
ON:DC11V or more
OFF:Less than DC5V
Note:
Even when an
external power supply
is used (in sink logic
mode, i.e., when
SINK (PLC) is
selected), connect the
reference
potential-side (0V
side) cable from the
power supply to the
CC terminal.
