Description
Dependent on
Shade type
Blind
Roller Shutter
This parameter can be used to determine which type of shade
is controlled on the particular channel.
Factor for the number
of degrees of angle for
step command (Basis 2°)
0–255
5
This parameter can be used for setting the increment for a step
command for the particular channel.
Factor for the number
of degrees of angle for
the adjustment during
sunshade positioning
(Basis 2°)
0–255
30
This parameter can be used for determining the angle for
adjustment in the lower sunshade position for the particular
channel.
and shade type
= “blind”
Factor for the number
of degrees of angle for
Up travel from lower
end position (Basis 2°)
0–255
30
This parameter can be used for determining the angle for
upward travel from the lower end position for the particular
channel. This can be used to tauten the cloth of awnings.
and shade type
= “roller shutter”
Adjust upwards
after manual downward
travel
locked
released
This parameter can be used to determine whether, for the
particular channel, an upward adjustment by the angle given
by the parameter "Adjustment during positioning of lower
position" occurs in the case of manual downward travel. An
upward adjustment will then also occur if a manual downward
movement is interrupted by a stop.
Factor for the number
of degrees of angle for
maximum opened slat
position (Basis: 2°)
0–255
45
This parameter is used to determine the angle of the slat posi-
tion from fully closed to fully opened for the particular channel.
and shade type
= “blind”
Factor for the number
of degrees of angle for
slat position from open
to shade height change
(Basis: 2°)
0–255
30
This parameter can be used, for the particular channel, to set
the angle by which the slats will turn when moving up or when
adjusting upwards beyond the fully opened position, before the
shade height changes.

Planning and activation
quently read out SMI positions. Moreover, this will be used to position the
blind slats so that shading situations can be recreated exactly, non-direc-
tionally and directly; the parametrisation of the slat geometry can be given,
however, in °.
Even during initial activation with drives with ready pre-programmed SMI
slave addresses, again no further programming of slave addresses is nee-
ded, just a calibration of the drives if necessary.
Initialisation using drives with non-programmed slave addresses
or slave address 0
If, during initialisation, no drives answer at one or more addresses preset
in accordance with the ETS, the actuator attempts to assign the missing
slave addresses to drives by re-programming. In this case there are two
possible addressing processes:
In the case of automatic addressing, the actuator uses the algorithm for
key ID search, as specified in the SMI standard. If the actuator finds a pro-
grammable slave (slave address 0), it will program the slave with the slave
address designated in accordance with the ETS. The highest key ID found
of the programmable drives will be assigned to the highest unallocated
slave address in accordance with the ETS.
In the case of key ID addressing, the actuator attempts to program those
drives with the unallocated slave addresses, the manufacturer and key ID
data of which are assigned to the slave address in accordance with the
ETS. If this attempt fails, the channel with this slave address remains
without function.
Initialisation using drives with slave addresses
already programmed
During initialisation (after bus reset, switch-on or download), the actuator
attempts to reference the available slaves, assigned per channel according
to the ETS parametrisation, using their SMI slave addresses. If the actuator
has already been taken into operation, it will have stored the manufacturer
and key ID entries for all the available drives in its non-volatile memory.
For each slave expected according to the ETS and found on the SMI, the
manufacturer and key ID entries are read out and compared with the stored
entries. If "per manufacturer and SMI key ID" addressing has been chosen,
a comparison occurs simultaneously with the drive data given in accord-
ance with the ETS. If no physical change has occurred to the slaves avail-
able on the SMI since the last activation, the actuator is then immediately
ready for operation.
If one or more drives have been exchanged in the meantime, the new drives
will answer but using the relevant slave address from the outset. This means
that, in the case of automatic addressing, manufacturer and key ID entries
that are detected as different by the actuator will be updated and stored.
In the case of key ID addressing, the drive data given in accordance with
the ETS must correspond to the data read out; otherwise the drives will not
be accepted by the actuator and will be ignored during operation.
On all channels that are configured as blinds, a calibration will then be car-
ried out for drives identified as exchanged. For this, the actuator initiates
an adjustment of the drive by a fixed angle of 500° in order to ascertain
the ratio of SMI positions in degrees by using the previously and subse-
