Emergency Off Mode
Program ⇒ Protection Settings ⇒ Emergency Off Mode Selection
This parameter determines the method used to stop the motor in the event that
an Emergency Off command is received.
This setting may also be associated with the FL terminals to allow the FL relay
to change states when an EOFF condition occurs by setting the FL terminal to
Fault FL (all).
Note: A supplemental emergency stopping system should be used
with the ASD. Emergency stopping should not be a task of
the ASD alone.
