Axis parameters
REFPULSE (P32)
It indicates the type of flank of the I0 signal that is used for home search.
REFDIREC (P33)
Indicates the direction of the home search in this axis.
REFEED1 (P34)
Indicates the axis feedrate when searching home until it hits the home switch.
REFEED2 (P35)
Indicates the axis feedrate when searching home after hitting the home switch until it finds the marker
pulse (Io).
REFVALUE (P36)
Indicates the position value of the machine reference point (physical location of the marker pulse)
with respect to machine reference zero.
The machine reference point is a point that the OEM sets on the machine to synchronize the system.
The CNC positions the axis at this point, instead of moving it to the machine zero point.
When the machine uses semi-absolute scales (with coded marker pulses), the axis may be homed
anywhere within its travel. Thus, this parameter must only be set when applying leadscrew error
compensation. The amount of leadscrew error of the machine reference point may have any value.
With Sercos connection, when the drive uses absolute feedback, instead of parameter
"REFVALUE", it takes into account its equivalent "SERCOS PP177" of the drive.
