Parameters
51
PTrim Select
Use PTrim Select to select the options for the process trim
regulator. If bits 0 and 1 are either both set or both clear, both the
speed and the torque references remain unaffected. If bits 3 and
4 are both set, bit 3 takes priority.
The bits are defined as follows:

Speed Trim
Set to trim the speed reference.
1
Torque Trim
Set to trim the torque reference.
2
Speed Input
Select the speed inputs.
Bit
Description
3
Set Output
Set the output option.
4
Preset Integ
Preset integrator option.
5
Trim Limiter
Force ON trim limit option.
Bit
Description
6
Trim Enable
Enable process trim. OR’d with
Process Trim bit 11 in Logic Input
Sts (parameter 14).

PTrim Filter BW
Use PTrim Filter BW to set the bandwidth of a single pole filter
used with the error input for process trim. The input to the filter is
the difference between PTrim Reference (parameter 49) and
PTrim Feedback (parameter 50). The output of this filter is used
as the input to the process trim regulator.
