5.3 Saving parameters to the drive
On the Unidrive SP, Affinity, Digitax ST and Commander SK to avoid loss of the
configured settings when the drive is powered down it is necessary to write 1000 to
Pr MM.00 followed by pressing the reset button to perform a drive save. On Mentor MP
Pr MM.00 needs to be set to a value of ‘SAVE’ followed by pressing the reset button.
To store drive parameters:
•Set Pr MM.00 to 1000 (Mentor MP Pr MM.00=SAVE).
• Press the red RESET button.
The drive will store all parameters (except Menu 20) but the operation of the SM-
EtherCAT will not be affected. Changes made to the SM-EtherCAT configuration
parameters will not take effect until the SM-EtherCAT is reset.
5.4 Re-initialising the SM-EtherCAT
Changes to the SM-EtherCAT configuration in menu 15, 16 or 17 parameters (menu 15
and 16 on Affinity, menu 15 on Commander SK) will not take effect until the SM-
EtherCAT has been re-initialised.
To re-initialise SM-EtherCAT:
1. Set Pr MM.32 to ON.
2. When the sequence has been completed, Pr MM.32 will be reset to OFF.
3. The SM-EtherCAT will re-initialise using the updated configuration.
5.5 Re-initialise all Solutions Modules
To re-initialise all Solutions Modules fitted on a Unidrive SP, Affinity or Digitax ST:
1. Set Pr MM.00 to 1070.
2. Press the red RESET button on the drive.
Unidrive-SP, Mentor MP, Affinity and Digitax ST: Menu 20 applications parameters may
be saved if an Application Module is fitted, menu 20 is stored in the Application
Module’s memory. See the relevant Application Module documentation for more
information. If the drive is running on backup supply only, Pr MM.00 must be set to 1001
to perform a save.
This saves only drive and module parameters and not SM-EtherCAT related objects.

The above sequence does NOT store the SM-EtherCAT configuration parameters in the
drive or the SM-EtherCAT’s internal FLASH memory. This parameter will change back to
off immediately and as such the change may not be visible on the display.
NOTE
This sequence does NOT store the SM-EtherCAT configuration parameters in the drive
or the SM-EtherCAT FLASH memory.
On Commander SK drives, Pr 00.00 is not available.
