MACHINE PARAMETERS
SOFT: V02.2X
Axis parameters
The communication with the drive is done through Sercos, feedback included.
X axis (main) SWINBACK of the X axis = 0.
Z axis (secondary) SWINBACK of the Z axis = 1.
The CNC internally switches the feedback it receives via Sercos and it supplies it to either axis
depending on the status of the SWITCH2 mark.
JERKLIM (P67)
It defines the derivative of the acceleration. It may be used to limit the acceleration changes to
smooth the machine movements on small speed increments or decrements and with FFGAIN values
close to 100%.
The CNC ignores this parameter when moving with electronic handwheels, mechanical
handwheels, look ahead, threading (G33) and rigid tapping.
The smaller the value assigned to JERKLIM, the smoother the machine’s response, but the acc/dec
time will be longer. When increasing the value of JERKLIM, it decreases the acc/dec time but the
machine response worsens.
Recommended values:
In millimeters JERKLIM = 82*G00FEED / ACCTIME**2
In inches JERKLIM = 2082*G00FEED / ACCTIME**2
Use parameter ACCTIME2 when adjusting the second set of parameters.
If the stability of the machine is affected by the values mentioned earlier, the JERKLIM value should
be lowered to half as much.
Possible values
Between 0 and 99999.9999 m/s
