Description
Description
Defines the delay time before the
drive will start after command is
issued. Start Delay (P3.2.9) must
be enabled.
Enable point for the interlock
application. If enabled, the drive will
energized the relay output defined
for DmprIntlckLogic when a start is
active. The drive will not start until
Run Interlock 1 (P3.5.1.12) and
Run Interlock 2 (P3.5.1.13) become
active if Mot. InterlockTimeout
(P3.1.12) is set to 0. Otherwise will
activate after the time defined in
Mot. InterlockTimeout (P3.1.12)
Defines the amount of time the
drive will wait for the interlock
feedback to be given before
starting.
0 = No timeout time used. Unit will
wait indefinitely for the feedback
before starting the drive.
> 0 = Unit will only wait this time for
the feedback, then start the drive.
Defines the run interlock proof
timeout time. If Run Interlock 1
(P3.5.1.12) or Run Interlock 2
(P3.5.1.13) do not activate within
the time defined, the response
action defined in Run Interlock Fault
(P3.9.29) will occur. This requires
Mot. Interlock Start (P3.2.11) to be
enabled.
