SLOW UP / SLOW DOWN [
UP-T
UP-T
/
DN-T
DN-T
]
It is same purpose as soft start function. Soft start starts
only one time at
fi
rst but slow up/slow down function start
during operation.
Regardless of control method setting (phase control or
cycle control), it operates as phase control.
When it reaches to the target output value, slow up/slow
down functions end.

Set range : 0 to 999 sec. (0 sec.: not using this function)

RESET
[
RST
]
This function is to limit output range to protect load.
•
Set range : 0 to 110%
(Output low limit value < Output high limit value)
After selecting RESET function, turn digital input
ON(close) and open, this unit resets and re-starts.
Below functions are available by terminal input.
Digital input has
fi
ve terminals; AUTO/MANUAL terminal,
RUN/STOP terminal, and DI-1 to 3 terminals.
Select the function for each input terminal of DI-1 to 3.
AUTO/MANUAL selection digital input
[no. 7 and 11 terminals]
RUN/STOP switching digital input
[no. 6 and 11 terminal]
DI-1 to DI-3(no. 1 to 3 of digital input ) terminal
[no. 8, 9, 10 and 11(COM) terminal]
Select AUTO(close)/MANUAL(open) input by terminal
input.
AUTO mode controls output according to control input
as analog input (voltage, current) or ON/OFF input
(including SSR pulse input).
MANUAL mode controls according to control input as
the inside VR adjustment or an outside VR adjustment.
When selecting AUTO (close), the front AUTO lamp
turns ON or selecting MANUAL(open), the front AUTO
lamp turns OFF.
Select RUN(close)/STOP(open) operation status by
terminal input.
RUN mode operates as the set contents by control
input. STOP mode is standby status.
When selecting RUN(close), the front RUN lamp turns
ON or selecting STOP(open), the front RUN lamp turns
OFF.
Select the each function for each digital input at
parameters [
DI-1
,
DI-2
,
DI-3
].
When setting ON(close) to DI input, the front EVT lamp
turns ON or setting OFF(open), the front EVT lamp
turns OFF.
As below, there are 6 functions to select.

Current limit [
C-LM
C-LM
]
It operates when normal, static voltage, static current
mode of phase control.
When using the load which has high inrush current, it
restrains the current to protect thyristor.
Especially, in case of voltage feedback, only voltage
current, it may over the rated current of thyristor because
current
fl
ows by resistance value of the load. To prevent
over the rated current, limit the current.
