When set-up as an analog input, this parameter can be used to invert the analog input reference (i.e. multiply the input scaling result by -1).
For digital input, this parameter selects a digital inversion.
As default, this parameter is set-up automatically according to the drive configuration (see Pr 11.27 on page 116).
Only non bit parameters which are not protected can be controlled by analog inputs. If a non valid parameter is programmed to the destination of an
analog input, the input is not routed anywhere.
After a modification to this parameter, the destination is only changed when a reset is performed.
The parameter required to be represented as an analog signal by the analog output on terminal B1, should be programmed in this parameter.
This parameter is used in conjunction with Pr 7.33 to determine the analog output signal. Pr 7.33 has 4 pre-determined settings for easy set-up of the
analog output. If the user requires to set Pr 7.19 to another parameter, then Pr 7.33 must be set to 4: USEr.
See Pr 7.33 for further details. If a non valid parameter is programmed as a source, the output will remain at zero.
Users wanting to output load should be aware of the maximum values of the parameters they are routing to the output.
The maximum value of Pr 4.02 (active current) is the maximum level of current that the drive can operate at which is drive rating x 1.5. Therefore, at
rated load the analog output will be 1/1.5 x 10 = 6.66V.
The maximum value of Pr 4.20 is the active current limit (Pr 4.18) and therefore the analog output will be at 10V when the load is at its maximum.
Users wishing to see 10V output at 100% load will need to set a scale factor in Pr 7.20 equal to Pr 4.18/100 to achieve this.
This parameters can be used to scale the analog output if so desired. However in most cases it is not necessary as the output is automatically scaled
such that when the source parameter is at its maximum, the analog output will be at its maximum.
