Function
The input terminal, for which the run permissive has been pro-
grammed, must be logic 1 before a start command can be ac-
cepted. Run permissive has a logic AND function related to the
terminal, which is programmed for [8] Start, [14] Jog, or [20]
Freeze Output. To start running the motor, both conditions must
be fulfilled. If run permissive is programmed on multiple termi-
nals, [52] Run permissive needs only be logic 1 on 1 of the termi-
nals to carry out the function. The digital output signal for run re-
quest ([8] Start, [14] Jog, or [20] Freeze output) programmed in
parameter group 5-3* Digital Outputs or parameter group 5-4* Re-
lays is not affected by run permissive.
If no run permissive signal is applied, but either run, jog,
or freeze commands are activated, the status line in the
display shows either Run Requested, Jog Requested, or
Freeze Requested.
A signal applied puts the drive into hand-on mode as if [Hand
On] was pressed on the LCP and a normal stop command is over-
ridden. If disconnecting the signal, the motor stops. To make any
other start commands valid, another digital input must be as-
signed to [54] Auto Start, and a signal applied to this. The [Hand
On] and [Auto On] keys on the LCP have no impact. The [Off] key
on the LCP overrides [53] Hand start and [54] Auto start. Press
either [Hand On] or [Auto On] to make [53] Hand start and [54]
Auto start active again. If there is no signal on neither [53] Hand
start nor [54] Auto start, the motor stops regardless of any nor-
mal start command applied. If signals are applied to both [53]
Hand start and [54] Auto start, the function is auto start. If press-
ing [Off] on the LCP, the motor stops regardless of the signal on
[53] Hand start and [54] Auto start.
This selection puts the drive into auto mode as if [Auto On] has
been pressed. The function is similar to [53] Hand start.
Increase signal to the digital potentiometer function described in
parameter group 3-9* Digital Pot. Meter.
Decrease signal to the digital potentiometer function described
in parameter group 3-9* Digital Pot. Meter.
Clears the digital potentiometer reference described in parame-
ter group 3-9* Digital Pot. Meter.
(Terminal 29 or 33 only). Input for increment counting in the SLC
counter.
