Watchdog Circuit; Saving Of Drive Parameters - Parker LINKnet AC30 Series Product Manual

Watchdog Circuit

It is recommended that a Watchdog Circuit be implemented in each LINKnet configuration to stop the drive if
there is a loss of Ethernet communications. Presently if there is a loss of Ethernet communications on the LINKnet
drive, it will continue to run and not fault. Within DSE there is a WATCHDOG INPUT function block located in
the BLOCK MENU. It can be connected to the DRIVE START Input in place of an INPUT Slot. It must be
updated with a logic True signal. If 5 seconds has passed and it is not updated with a logic True, the Output of the
block will go False and the drive will stop and not fault. This WATCHDOG can also be connected to a Digital
Output which can be monitored by the user to take further action. For more information on this function block, see
the Help Data sheet within DSE.

Saving of Drive parameters

AC30 Series LINKnet Product Manual HA474739U001
If a parameter is changed via the GKP (Graphical Keypad) or when ON LINE when using DSE, to save
the parameters, the parameters must be saved. This can be done while using DSE and go to Command /
Parameter Save or via the GKP by going to Setup / Environment / Save ALL Parameters and setting
this value to True or Parameters / Device Manager / Device Commands / Save ALL Parameters and
setting this value to True.
If you want the parameters to be saved automatically any time a parameter is changed via the GKP or
when ON LINE with DSE, set the Enable Auto Save to True in the Setup Wizard function block. To set
it from the GKP go to Parameters / Device Manager / Setup Wizard. Set Enable Auto Save to True.
Now anytime a parameter is changed it will be saved automatically every 100ms.
