VLT® Flow Drive FC 111
Programming Guide
[11]
Start reversing
Use for start/stop and for reversing at the same time. Signals on [8] Start are not allowed at the same
time. 0 = stop, 1 = start reversing.
[14]
Jog
Used for activating jog speed. See parameter 3-11 Jog Speed [Hz]. (Default digital input 29).
[16]
Preset ref bit 0
Enable a selection of 1 of the 8 preset references according to
[17]
Preset ref bit 1
Enable a selection of 1 of the 8 preset references according to
[18]
Preset ref bit 2
Enable a selection of 1 of the 8 preset references according to
[19]
Freeze refer-
Freeze actual reference. The frozen reference is now the point of enable/condition for speed up and
ence
speed down to be used. If speed up/speed down is used, a speed change always follows ramp 2 (pa-
rameter 3-51 Ramp 2 Ramp Up Time and parameter 3-52 Ramp 2 Ramp Down Time) in the range parame-
ter 3-02 Minimum Reference - parameter 3-03 Maximum Reference.
[20]
Freeze output
Freezes actual reference. The frozen reference is now the point of enable/condition for speed up and
speed down to be used. If speed up/speed down is used, the speed change always follows ramp 2.
[21]
Speed up
For digital control of the up/down speed (motor potentiometer). Activate this function by selecting
either freeze reference or freeze output. When speed up is activated for less than 400 ms, the resulting
reference is increased by 0.1%. If speed up is activated for more than 400 ms, the resulting reference
ramps according to ramp 1 in parameter 3-41 Ramp 1 Ramp Up Time.
[22]
Speed down
Same as [21] Speed up, but reference decreases.
[23]
Set-up select
Selects 1 of the 2 setups. Set parameter 0-10 Active Set-up to multi setup.
bit 0
[32]
Pulse input
Select pulse input when using a pulse sequence as either reference or feedback. Scaling is done in
parameter group 5-5* Pulse Input. Available only for terminal 29.
[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 permissive
The input terminal, for which the run permissive is programmed, must be logic 1 before a start com-
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* Digital Outputs, or parameter group 5-4* Relays.
[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.
[54]
Auto start
A signal applied puts the drive into auto-on mode as if [Auto On] is pressed. See also [53] Hand Start.
[60]
Counter A (up)
Input for increment counting in the SLC counter.

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.
