Reset SynchLink
After setting up the configuration SynchLink must be reset on both drives in one
of the following ways:
• Set parameter 904 [SL Node Cnfg], bit 3 “Reset SL” = 1 on the drives.
This bit will automatically transition back to 0 after SynchLink is reset.
OR
• Perform a reset on the drives. This can be done via the HIM by navigating
from the Main Menu to Diagnostics > Faults > Reset Device.
OR
• Cycle power on the drives.
Sync Generator The sync generator can be used to synchronize a parameter and delay it one scan.
This can be used in conjunction with SynchLink (Refer to
SynchLink on
page 180 for more information).
Configuration
