9.9 Ramp/Soak Control
Ramp/Soak control is possible by using Area soak time, Link area number and Setting change rate limiter
(up/down) in Parameter setting mode (P. 31). The operating procedure is described in the following.
1.
Press the SET key several times at Parameter setting mode
until Input 1_setting change rate limiter (up) setting screen
is displayed.
2.
Press the UP key to change the number to 5.0.
3.
Press the SET key to store the new value. The display goes
to the next parameter. Check that this screen is set to OFF.
4.
Press the SET key until Area soak time setting screen is
displayed.
5.
Press the shift key to high-light the most significant digit.
6.
Press the UP key to change the number to 6.
7.
Press the SET key to store the new value. The display goes
to the next parameter.
8.
Press the UP key to change the number to 2.

* In this example, the Area soak time for Memory
area 3 is set. However, as the Area soak time for
the memory area linked last becomes invalid, the
state of SV3 reached continues.
The unit time can be changed by the Setting
change rate limiter and the Soak time unit
selection in the Engineering mode. (P.97)
