Servo-Control
Words N0 to N31 define threshold 1, which is the maximum permissible error (in internal measurement units) after
synchronisation. Above this threshold, the system generates an error but allows the driven axis to be resynchronised
on its drive axis. The basic value is 160 μm.
Words N32 to N63 define the correction coefficient (in 1/1000) for each axis. It is a fraction of the error reinjected into
the driven axis servo-loop to achieve synchronisation. The basic value is 250.
Word N64 defines threshold 2, which is the maximum synchronisation error (in internal measurement units) tolerated
for all the axis pairs. Above this value, the system generates an error and inhibits synchronisation. The basic value
is 600 μm.
The internal units can be mm/10, mm/100, μm, μm/10 or μm/100 for linear axes (see 4.8) and deg/1000 for rotary axes.
REMARK: The error generated when thresholds 1 and 2 are exceeded causes reset of
CN_PRET and display of error 39 on the «AXIS» page.
