16 Improved drive parameter management
From this version on, it also possible to save and load into a
peripheral device or PC the drive parameter tables via Sercos serial
line.
For that, select the parameter page of the desired drive at the CNC
and press the relevant softkey.
A file saved from the CNC via WINDNC may be loaded into the drive
via DDSSETUP and vice versa.
17 User and OEM arithmetic parameters
There are now two new ranges of global arithmetic parameters.
For compatibility with previous versions, global arithmetic
parameters P100-P299 are maintained and may be used by the
user, by the OEM and by the CNC cycles.
There are now 2 new tables of global arithmetic parameters.
Changing an OEM parameter requires an OEM password.
OEM parameters and subroutines having OEM parameters may
only be written in OEM programs having the [O] attribute.
On the MC and MCO models, when using OEM parameters in the
configuration programs, these programs must have the [O] attribute.
If they don't, an error will be issued when editing a user cycle that
refers to OEM parameters in write mode.
General machine parameters “ROPARMIN” and “ROPARMAX” may
be used to protect any global parameter (user and OEM included)
against being written.
There is no restriction to read these parameters.
18 Exponential type of leadscrew backlash peak
The additional command pulse used to make up for the possible
leadscrew backlash in movement reversals may be rectangular or
exponential.
If the duration of the rectangular pulse is adjusted for low speed, it
could be excessive for high speed or insufficient for low speed when
adjusted for high speed.
In this cases, it is recommended to use the exponential type that
applies a strong pulse at the beginning and decreases in time.
User parameters Range: P1000 - P1255.
OEM parameters Range: P2000 - P2255
Arithmetic parameter tables available:
GUP Global parameters P100-P299
USP User parameters P1000-P1255
OEP OEM parameters P2000 - P2255
