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.
See Pr 14.13 and Pr 14.14.
