Ax
is parameters
FBACKAL (P11)
This parameter is to be used only when the feedback signals are sinusoidal or differential (double
ended).
Indicates whether the feedback alarm for this axis will be ON or OFF.
FBALTIME (P12)
It indicates the maximum time that the axis may stay without properly responding to the CNC’s
command.
Depending on the command for an axis, the CNC calculates the number of feedback pulses that
it must receive for each sample period.
The axis will be considered that it is working fine when the number of pulses received is between
50% and 200% of the calculated number.
If at any time, the number of feedback pulses received is out of this range, the CNC will keep checking
that axis until it detects that the number of pulses received has come back to normal. But if more
time elapses than the one indicated in this parameter without the axis coming back to normal, the
CNC will issue the relevant error message.
AXISCHG (P13)
Indicates the counting direction. If correct, leave it as is, but to change it, select YES if it was set
to NO and viceversa. When changing this parameter, also change axis parameter LOOPCHG (P26).
BACKLASH (P14)
Indicates the amount of backlash. Enter 0 when using linear encoders.
LSCRWCOM (P15)
Indicates whether the CNC should apply leadscrew error compensation or not.
