The V axis is the gate/door speed, T axis is the time required by the door/gate to move from a limit switch to the other. The parameters
govern both the opening and the closing phases.
At gate/door stopped on any SWO (SWC) limit switch, when a control key is pressed the gate/good starts moving and reaches the
standard operating speed, which can be adjusted by FSTO/FSTC parameter.
The TACC time sets how rapidly the gate/door should reach the standard speed.
Before meeting the SWX (SWO) stop limit switch, braking preset by TSM time will start.
Braking leads the gate/door from standard speed (FSTO/FSTC) to braking speed, adjusted by SLDO/SLDC parameter.
The TDEC time sets how rapidly the gate/door should reach the braking speed.
The TDEC time is theoretical by reason of the fact that as soon as the speed reaches the value preset by SLDS, braking at constant
speed starts until reaching the SWC (SWO) limit switch.
Once the limit switch is reached, the gate/door continues its movement for a period of time adjusted by BLC parameter, until entire stop.
The following diagram shows graphically the stroke of the leaf in case that one of the safety input is activated (STOP/PHOT/BAR):

The safety input intervention causes an immediate slowing-down of the leaf, the time in which the leaf switches from the standard speed
to the slowdown one is adjustable though the value TBR and it must respect the values indicated on the Table 1.
IMPORTANT:
- For the correct operation of parameters it is mandatory that the AUTOSET be carried out correctly (see STROKE LEARNING).
- If the FSTO/FSTC speed is increased, TSMO/TSMC, TACC and TDEC values must be increased proportionally in order to avert any
mechanical stress to the gear motor.
- The TBR value must be set as shown on the Table 1. A value of TBR too short on a leaf with a lot of inertia can damage the automa-
tion.
A TSMO/TSMC value, which is too short, combined with a TDEC value, which is too high, might result in the cancellation of the SLDO/
SLDC braking phase due to the gate leaf friction and the triggering of the limit switches when the speed is still high.
This situation must be absolutely avoided.
- The AUTO function does not change the default values of the above-mentioned parameters. The latter must be preset by the installer
according to the gate/door specifications.
- On the BAR input will be cabled in series to the SAFETY EDGE (or SAFETY EDGES) also a N.C. contact which opens every time that
the motor is released or the cover is removed. Thus, in case that 1. Control unit powered, 2. Motor not in movement, 3. SWO and
SWC not engaged (motor not on the limit switch), if the input BAR is activated and afterwards reactivates (motor not in movement
and cover on ready to start the maneuver), to the next command of PP/OPEN/CLOSE (also radio command) it is necessary force a
slow speed maneuver.
7) AUTOSET
The stroke learning is essential for the good setting of the slowdown function, this is done by means of the AUTO function described
above and also when the first complete maneuver is performed (without interruptions) from SWO to SWC) (or vice versa).
