Resetting the Adapter Changes to switch settings and some adapter parameters require that you
reset the adapter before the new settings take effect. You can reset the
adapter by cycling power to the drive or by using Parameter 14 - [Reset
Module].
Set Parameter 14 - [Reset Module] to “1” (Reset Module).
Figure 3.8 Example Reset Module Screen
When you enter “1” (Reset Module), the adapter will be immediately reset.
When you enter “2” (Set Defaults), the adapter will set all adapter
parameters to their factory-default values. After performing a Set Defaults,
enter “1” (Reset Module) so that the new values take effect. The value of
this parameter will be restored to “0” (Ready) after the adapter is reset.
!
ATTENTION: Risk of injury or equipment damage exists. If the
adapter is transmitting control I/O to the drive, the drive may fault
when you reset the adapter. Determine how your drive will
respond before resetting a connected adapter.
