P415 (limitation +/-) [%]
: Controller limitation (see above)
Note:
In the function process controller, parameter P415 is used as a controller
limiter downstream from the PI controller. This parameter therefore has a
double function.
Example 25% of setpoint
P416 (ramp before controller) [s]
: Factory setting 2s (if necessary, adjust to controller behaviour)
P420 (Funct. Switch digital input 1)
: "1" Enable right
P421 (Funct. Switch digital input 2)
: "40" actual value PID process controller (only with Basic I/O or Standard I/O)
Alternatively, the 2
nd
analog input (P405=14) of the multi I/O can be used.
