■ Soft Start [

] and start limit time [
S-LT S-LT

■ Output slope manual adjustment [

■ BASE-UP [

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
fi nal target output value
is 50%, taken time to reach is t/2.
Reaching time to the final target output value = Target
output (%)× t
※
Ex) SOFT START sec., fi nal target output : 80%
0.8×25 = 20sec
•
Set range : 0 to 100 sec. (0 sec.: not using this function)
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.
•
Set range for start limit: 0 to 110% of output
•
Set range for start limit time : 0 to 100 sec.
(0 sec.: not using this function)
This function is to adjust manually (inside or outside VR)
output value ratio for control input.
When AUTO operation and output slope manual
adjustment[
A-GA ] is set as ON, [ SLOP ] is not able to
set.
It displays slope value by the inside or outside VR input.
This function is to add base-up set value to input signal. It
is available only when output low-limit value is 0%.
It is limited by start limit value at initial start.
• Set range : BASE-UP SV(%) < Output high-limit value
•
Output value for BASE-UP setting
: Input(%)×Slope value+ BASE-UP SV
■ Output slope setting [
SLOP 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 slope manual adjustment [ A-GA ] as ON
: Set output slope by the inside 3-level slide switch
