3-wire operation (
CW
=
)
Can be operated by a momentary push-button. HD (operation holding) is assigned to the terminal S3. A self-
holding of operations is made in the inverter by connecting the stop switch (b-contact) to the S3 terminal and
connecting the running switch (a-contact) to the F terminal or the R terminal.
Refer to 7.2(3) for details.
External input UP/DOWN setting (
CW
=
)
Allows setting of frequency with the input from an external contact. Can be applied to changes of frequen-
cies from several locations.
UP (frequency up signal input from external contact) is assigned to the S1 terminal, and DOWN (frequency
down signal input from external contact) are assigned to the S2 and CLR (frequency up/down clear signal
input from external contact) are assigned to the S3 terminals respectively. Frequencies can be changed by
input to the S1 and S2 terminals.
Refer to 6.5.2(3) for details.
4-20 mA current input(
CW
=
)
Used for setting frequencies with 4-20mA current input. Switching between remote control and manual con-
trol (different frequency commands) can be made by turning on or off the S3 terminal, because FCHG
(forced change of frequency commands) is assigned to the S3 terminal with priority to current input.

Function
These parameters are used to specify which input device (operation panel or terminal board) takes priority
in entering an operation stop command or a frequency setting command (internal potentiometer, VIA, VIB,
operation panel, serial communication device, external contact up/down, VIA+VIB).
