This is the gain applied to the PID error before being integrated. See 14.08 .
This is the gain applied to the PID error before being differentiated. See 14.08 .
If parameter 14.18 is set to 0 this is the maximum positive PID output, and if 14.18 is set to 1 this is a symmetrical limit on the
PID output.
The maximum negative or minimum positive PID output can be limited by this parameter if parameter 14.18 is set to 0. This
parameter has no function if parameter 14.18 is set to 1.
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.
This 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. If the PID is disabled, the integral value will always be reset
to 0.
When this parameter is set to 1, 14.13 is used as a symmetrical limit on the PID output, while if it is set to 0 the positive and
negative limits can be set differently with parameters 4.13 and 4.14 .
This parameter monitors the Main reference input of the PID controller.
