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 PID output is scaled by this parameter before being added to the main reference. After the addition to the main reference, the output is
automatically scaled again to match the range of the destination parameter.
The destination parameter should be set up with the parameter that the PID controller is to control. Only non-bit parameters which are not protected
can be controlled by the PID function. If a non valid parameter is programmed the output is not routed anywhere. If the PID is to control speed then it
is suggested that one of the preset speed parameters is entered here.
When this parameter is set to 0 the integrator operates normally. Setting this parameter to 1 will cause the integrator value to be held as long as the
PID is enabled when the drive is disabled. 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 on page 143.
This parameter monitors the main reference input of the PID controller.
