Process Trim Data
[Proc Trim Data]
This is the reference input value for pro-
cess trim. The Process Trim Output is up-
dated based on the value of this input.
This is the feedback input value for pro-
cess trim. The Process Trim Output pa-
rameter is updated based on the value of
this input.
This is a bit coded word of data containing
several selection options for the process
trim regulator as follows:
Bit 0 Trim the Velocity Reference
Bit 1 Trim the Torque Reference
Bit 2 Select Velocity Inputs
Bit 3 Set Output Option
Bit 4 Preset Integrator Option
Bit 5 Force ON Trim Limit option
This parameter is used to preset the output
of the process trim regulator when either
the “Set Output Option” or “Preset Integra-
tor Option” is selected in parameter 29.
This parameter determines the bandwidth
of a single pole filter used with the error
input for process trim. The output of this
filter is used as the input to the process
trim regulator.
Process Trim KI Gain
[Proc Trim Ki] Parameter Number 32
Parameter Type Sink
Display Units x.xxx
Drive Units 4096 = 1.000 Ki gain
Factory Default 1.000
Minimum Value 0.000
Maximum Value 16.000
This parameter controls the integral gain of
the process trim regulator. If process trim
equals 1.0, then the process trim PI regula-
tor output will equal 1 pu in 1 second, for 1
pu process trim error.
