CNC VARIABLES.

(REF: 1402)

Variables related to loop adjustment.
GAIN SETTING VIA PLC.
(V.)[ch].A.PLCFFGAIN.xn
(V.)[ch].A.PLCFFGAIN.sn
(V.)[ch].SP.PLCFFGAIN.sn
Variable that can be read and written from the PLC and read from the program and from the interface.
Variable valid for rotary and linear axes as well as for spindles.
The variable returns the execution value; reading it interrupts block preparation.
Percentage of feed-forward programmed from the PLC.
Syntax.
·ch· Channel number.
·xn· Name, logic number or index of the axis.
·sn· Name, logic number or index of the spindle.
Remarks.
In order for the feed-forward and the AC-forward defined this way to be taken into account,
they must be active by machine parameter; i.e. by means of machine parameter FFWTYPE
if it is an analog drive or a simulated drive or parameter OPMODEP if it is a Sercos drive.
The values defined by these variables prevail over the ones defined by machine parameters
or by program. Setting the variables with a negative value cancels their effect ("0" is a valid
value). These variables are initialized neither by a reset nor when validating the parameters.
The reading from the PLC will be given in hundredths (x100); i.e. if the parameter value is
·10·, the PLC reading will return a value of ·1000·.
