slope in the SP ramp unit.)

LSP ramp down slope

•
If the initial value is 0.0, the SP ramp does not operate. Therefore, by setting the
up slope to greater than 0.0 and setting the down slope to 0.0, the SP ramp can
be set to function only when the SP is increasing, not when the SP is decreasing.
This setting can be reversed so that the SP ramp functions when the SP is
decreasing but not when the SP is increasing.
•
Under the following conditions, if the SP ramp is set to enable both up and down
slopes, the ramp starts with the current SP as the starting point.
•
When the LSP value changed
•
When the SP group changed
•
When the mode changes from RSP to LSP
•
Under the following conditions, if the SP ramp is set to enable both up and down
slopes, the ramp starts with the current PV as the starting point.
•
At power on
•
When the mode switches from READY + AUTO mode to RUN + AUTO mode
•
When the mode switches from RUN + MANUAL mode to RUN + AUTO mode
•
When fixed value output is cleared
•
When the mode switches from pattern operation mode to constant value
operation mode
•
The SP lamp does not operate under the following conditions.
•
In MANUAL mode
•
In READY mode
•
In RSP mode
•
When the loop type is internal cascade and under the following conditions, if the
SP ramp is set to enable both up and down slopes on the master side, then the
ramp starts with the current master-side PV as the starting point.
•
When the slave switches from READY + AUTO mode to RUN + AUTO mode
