If Pr
14.18
= 0, the upper limit (Pr
14.13
) defines the maximum positive output for the PID controller and the lower limit (Pr
14.14
) defines the
minimum positive or maximum negative output. If Pr
14.18
= 1, the upper limit defines the maximum positive or negative magnitude for the PID
controller output. When any of the limits are active the integrator is held.
The value written to the destination parameter is (PID controller output x scaling) + PID main reference.
When this parameter is set to 0 the integrator operates normally. Setting this parameter to 1 will cause the integrator value to be held. Setting this
parameter does not prevent the integrator from being reset to zero if the PID controller is disabled.
