Machine Constant
Parameter
Function Settings
MC_4024:
U Continuous Path
Range
Type the desired U-axis range, or
accept the default.
NOTE:
MC_2351: U In-position
Tolerance Range must be smaller than
MC_4024: U Continuous Path Range.
Range (0.0000–9.0000)
0.0700 (inches) [Default]
Position Error Check (PEC) Setup Parameters
MC_4030:
Position Error
Checking
The CNC detects a loss of motion and
declares an error via the Position Error
Check (PEC) algorithm. You can
configure the parameters for these
calculations.
WARNING: The Position Error
Check parameter must be enabled
for the CNC system to be able to
declare a servo fault and shut
down the system in an emergency.
If the PEC algorithm detects a fault, the
servos shut off and the CNC displays
one of the following messages:
ERROR: (AXIS) LAG OVER MAX!
ERROR: LOST (AXIS) FEEDBACK!
Yes
(enabled) [Default]
No (disabled)
MC_4031:
PEC Check idle time
(ms)
The amount of time, in milliseconds,
allowed between the internal command
for a move and the input of counts from
the feedback device, indicating motion.
Range (25.00–5000.00)
100.00 (ms) [Default]
MC_4032:
PEC Maximum lag
error
The error distance allowed at rest or
low feedrates, before declaring a fault.
Range (0.0000–2.5400)
0.0200 (mm) [Default]
Jog Return Position Setup Parameters
MC_4050:
X Jog position
X jog position defines a point on the
machine X-axis in reference to Machine
Home to which the CNC will return
when the Jog and Return function is
activated.
In Auto and S.Step Modes, use the Jog
and Return function to remove the tool
from the part without aborting the
program. It can be used to change a
tool or inspect a critical dimension
during normal operation.
Range (-9999.0000–25400.0000)
0.0000 [Default]
