VLT® HVAC Drive FC 131
Programming Guide
[34]
Ramp bit 0
Select which ramp to use. Logic 0 selects ramp 1, while logic 1 selects ramp 2.
[37]
Fire Mode
A signal applied puts the drive into fire mode and disregards all other commands. See parameter group
24-0* Fire Mode.
[52]
Run permis-
The input terminal, for which the run permissive is programmed, must be logic 1 before a start com-
sive
mand can be accepted. Run permissive has a logic AND function related to the terminal, which is pro-
grammed 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 terminals, run permissive only has to be logic 1
on 1 of the terminals for the function to be carried out. Run permissive does not affect the digital output
signal for run request ([8] Start, [14] Jog, or [20] Freeze Output) programmed in parameter group 5-3* Digi-
tal Outputs, or parameter group 5-4* Relays.
If no run permissive signal is applied but either run, jog, or freeze commands is activated, the status
line in the display shows either Run Requested, Jog Requested, or Freeze Requested.
[53]
Hand start
A signal applied puts the drive into hand on mode as if [Hand On] is pressed and a normal stop com-
mand is overridden. If the signal is disconnected, the motor stops. To make any other start commands
valid, assign another digital input to Auto Start and apply a signal. The [Hand On] and [Auto On] keys
have no impact. The [Off] key overrides Hand Start and Auto Start. Press either [Hand On] or [Auto On] to
reactivate Hand Start and Auto Start. If there is no signal on Hand Start or Auto Start, the motor stops
regardless of any normal start command applied. If a signal is applied to both Hand Start and Auto Start,
the function is Auto Start.

Auto start
A signal applied puts the drive into auto mode as if [Auto On] is pressed. See also [53] Hand Start.
