Gain setting.
PROGAIN
Proportional gain.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0.0 to 100.0 (1000/min).
Default value: 1.
Associated variable: (V.)[ch].MPA.PROGAIN[set].xn
This parameter sets the following error (difference between the theoretical instantaneous
position and the actual - real - axis position) for a particular feedrate.
FFWTYPE
Pre-control type.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: OFF / Feed Forward / AC-Forward / Feed F AC-Forward.
Default value: OFF
Associated variable: (V.)[ch].MPA.FFWTYPE[set].xn
This parameter indicates the type of pre-control for adjusting the gains.
In order to be able to modify the override while threading (parameter THREADOVR), the feed
forward must be active and higher than 90%. Feed forward may be defined with a lower value
than 90% in parameter FFGAIN and may be modified later on from the PLC using variables.
FFGAIN
Percentage of Feed-Forward in automatic.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: from 0 to 120 %.
Default value: 0.
Associated variable: (V.)[ch].MPA.FFGAIN[set].xn
The CNC only takes this parameter into account when working with feed forward; parameter
FFWTYPE if it is an analog or simulated drive and OPMODEP if it is a Sercos drive. This
parameter should only be used when working with non-linear acceleration and deceleration.
An axis that is going to work as an independent axis should have the same feed forward value
in automatic and in jog modes; in other words, parameters FFGAIN and MANFFGAIN should
be the same.
The scale for the following error of 800 µm per square.
Example:
To obtain a following error (E) of 1 mm for a feedrate (F) of 1000 mm/min. (a gain of 1).
F = E x PROGAIN
F / E = 1000 (mm/min) / 1 (mm) = 1000 / min
PROGAIN = 1
