corresponding parameters overwritten. The servo-control data will not be read, so
those parameters will remain unchanged in the E-727.
If you have optimized some parameters for your application, PI recommends that you repeat your
optimization routine with any new stage, because there are variations, e.g. in the stiffness and
natural frequency, of stages.
Upgrade or Repair of Stages
If you send your stage to PI, e.g. for upgrade or repair, the calibration data stored in the ID-chip
might be changed in the process. However, when you reconnect this stage to the E-727 to which it
was connected before, the firmware will detect that the type and serial number are unchanged
and will not read the new ID-chip data.
To force the E-727 to read the complete data of the ID-chip of the connected stage when the E-727
is switched on, you can enable the "Power Up Read ID-Chip" option (parameter ID 0X0F000000).
This has to be done for each input signal channel separately. Note that it might be necessary to
switch to a higher command level to have write access to that parameter (use CCL or the
appropriate facilities of PIMikroMove). Proceed as follows:
1.
In the PIMikroMove main window, open the
Device Parameter Configuration
window (
E-727…
> Parameter Configuration
) and select the
System Mechanics
groups where you can enable
the option. When this is done for all input signal channels associated with the stage, press the
Write selected edit values to default settings
button in the icon bar of the
Device Parameter
Configuration
window. Alternatively you can use the following commands in a terminal to
enable the option:
SEP 100 1 0X0F000000 1
for input signal channel 1
SEP 100 2 0X0F000000 1
for input signal channel 2 , etc.
2.
Now reboot the E-727 by typing the
RBT
command in the terminal (alternatively you can
power-cycle the E-727). This time all data is read from the ID-chip and stored in the E-727.
3.
To ensure that at next power-on or reboot the E-727 will not read all data again and overwrite
parameters you may have optimized, you will have to disable the "Power Up Read ID-Chip"
option, again for each input signal channel separately. In PIMikroMove, proceed as described
above in step 1 but make sure that the parameter now has the value "disabled". Alternatively
you can use the following commands in a terminal to disable the option:
SEP 100 1 0X0F000000 0
for input signal channel 1
SEP 100 2 0X0F000000 0
for input signal channel 2, etc.
If you had optimized parameters before the repair/upgrade, PI recommends you to repeat your
optimization routine when the stage is returned.
