Output slope setting [ SLOP]
This function is to set output changed ratio by control input
from 0.00 to 1.00 range.
•Output value when setting slope: Input (%)×Slope value
Output (%)
Control input signal (%)
Output slope
value (%)
Start limit [ S-LM ] and start limit time [ S-LT]
When power is ON, changing to RUN status from STOP
status, or alarm reset, set limit output value and time to
prevent the inrush current or error current.
Regardless of control method setting (phase control or
cycle control), it operates as phase control.
•Setting range for start limit: 0 to 110% of output
•Setting range for start limit time: 0 to 100 sec
(0 sec: not using this function)
• A: SOFT START function ends
• B: SLOW UP function ends
• C: SLOW DOWN function ends

SLOW UP / SLOW DOWN [ UP-T/ DN-T ]
It is same purpose as soft start function. Soft start starts
only one time at 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.
•Setting range: 0 to 999 sec

SOFT START [ ST-T ]
When controlling the load which has inrush current
(platinum, molybdenum, tungsten, infrared lamp, etc)
in power ON, or when control input changes rapidly, it
prevents the load to increase output gradually within the
set time. Set the time for soft start.
Regardless of control method setting (phase control or
cycle control), it operates as phase control.
Set the time to reach output from 0 to 100%.
It operates when it is RUN mode from STOP status after
supplying power or reset. When it reaches to the target
output value, soft start function ends.
Soft start set time (t) is the time up to 100% increase of
output applied to load. When the nal target output value
is 50%, taken time to reach is t/2.
Reaching time to the nal target output value = Target
output (%)× t
※E.g.)
SOFT START time: 25 sec, nal target output: 80%
0.8×25 = 20 sec
