the motor, both conditions must be fulfilled. If Run Permissive
is programmed on multiple terminals, Run permissive needs on-
ly be logic ‘1’ on one of the terminals for the function to be
carried out. The digital output signal for Run Request (
Start
[8],
Jog
[14] or
Freeze output
[20]) programmed in par. 5-3* Digital
outputs, or par. 5-4* Relays, will not be affected by Run Per-
missive.

Hand start
A signal applied will put the frequency converter into Hand mode
as if button
Hand On
on the LCP has been pressed and a normal
stop command will be overridden. If disconnecting the signal,
the motor will stop. To make any other start commands valid,
another digital input must be assign to
Auto Start
and a signal
applied to this. The
Hand On
and
Auto On
buttons on the LCP
has no impact. The
Off
button on the LCP will override
Hand
Start
and
Auto Start
. Press either the
Hand On
or
Auto On
button
to make
Hand Start
and
Auto Start
active again. If no signal on
neither
Hand Start
nor
Auto Start
, the motor will stop regardless
of any normal Start command applied. If signal applied to both
Hand Start
and
Auto Start
, the function will be
Auto Start
. If
pressing the
Off
button on the LCP the motor will stop regardless
of signals on
Hand Start
and
Auto Start
.
