SP ramp control
function
0: Function disabled
1: SP ramp control 1.
(In SP ramp-up: ramp 1, in SP
ramp-down: ramp 2)
2: SP ramp control 2.
(In external contact OFF: ramp
1, in external contact ON:
ramp 2)
0 The SP change ramp level (the rate
of change per second) can be set to
a constant value for control startup
and setting flow rate changed.
Setting of ramps 1 and 2 is done in
parameter setup mode.
5-2 Parameters (P. 5-12).
In case of SP ramp control 2, the
operation is performed by ramp 2
when “12” is selected in either one
of
C-1 0
to
C-1 2
(external contact
input function assignment) and also
when the target contact is ON, but
otherwise operation is performed by
ramp 1. If "7" is selected anywhere
in
C-1 0
to
C-1 2
, SP ramp control
is performed only when the target
contact is ON.
C-28
Analog scaling
function
0: Function disabled
1: Function enabled
0 The flow rate at analog input / out-
put 100% (5 V) can be optionally set.
The flow rate is set in parameter
setup mode.
5-2 Parameters (P. 5-12).
C-29
Forced PV
(instantaneous flow
rate) zero function
0: Function disabled
1: Function enabled
0 Instantaneous flow rate is made zero
forcibly after the flow rate is set to
zero or the mode is changed to valve
forced fully closed mode and delay
time has elapsed.
Instantaneous flow rate variation in
zero position caused by the inclina-
tion of pipe is neglected.
Delay time is set in parameter setup
mode.
5-2 Parameters (P. 5-12).

C-35
SP limit function 0: SP limit function disabled
1: Only upper limit enabled
2: Only lower limit enabled
3: Upper and lower limits
enabled
0 The upper and lower limit values of
the flow rate setup range can be set
to desired levels.
Upper and lower limits are set in
parameter setup mode.
5-2 Parameters (P. 5-12).
