Axis parameters
JOGFEED (P43)
Indicates the feedrate F assumed in the JOG mode if no feedrate is active.
PRBFEED (P44)
Indicates the probing feedrate when calibrating a tool in "JOG" mode.
MAXCOUPE (P45)
Indicates the maximum difference allowed between the following errors of the axes electronically
coupled (by program, PLC or as Gantry axes).
This value is only assigned to the slave axis.
ACFGAIN (P46)
Indicates whether or not the value assigned to axis parameter DERGAIN (P24) is applied onto the
variations of the programmed feedrate (AC-forward).
In a digital servo system, axis parameter ACFGAIN(P46) must be set to ADVANCED. This parameter
setting allows a smoother and more stable adjustment of the machine using a lot lower DERGAIN
values than those used when axis parameter AFCGAIN(P46) =YES. This is valid for axes and
spindles.
All axes of the channel, CNC or PLC, must have the same value for axis parameter ACFGAIN(P46).
When setting ACFGAIN=ADVANCED in an analog system, it will be treated as AFGAIN=YES.
Possible values
Between 0.0001 and 199999.9999 degrees/min or mm/min.
Between 0.00001 and 7874.01574 inches/min.
Default value: 1000 mm/min.
Possible values
Between 0.0001 and 99999.9999 degrees/min or mm/min.
Between 0.00001 inches/min and 3937.00787 inches/min.
Default value: 100 mm/min.
Possible values
Between 0.0001 and 99999.9999 degrees or millimeters.
Between 0.00001 and 3937.00787 inches.
Default value: 1 mm.
Value Meaning
EZ It is applied on variations of following error (derivative gain).
YES It is applied on the variations of the programmed feedrate that are due to
acceleration/deceleration (AC-forward).
ADVANCED It is used in a digital drive system and provides a smoother and more stable adjustment
of the machine.
Default value: YES
If the value of axis parameter ACFGAIN (P46) is changed, DERGAIN will have to be readjusted.
