H9 ASD Installation and Operation Manual 183
Emergency Off Mode Settings
Program Protection Emergency Off Settings
This parameter determines the method used to stop the motor in the event that
an Emergency Off command is received and the system is configured to use
this feature.
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) (see F132).
Note: A supplemental emergency stopping system should be used with
the ASD. Emergency stopping should not be a task of the ASD
alone.
