Command
Description
Static commands
UP
UP The commands can have an
additional pulse at the end
(same direction)
DOWN2
DOWN
DOWN1
DOWN to middle position (3
rd
end switch)
STOP
Stop
Relative commands
RUN_UP These commands contain one direction only (UP, DOWN) and one
pulse length. They are used specifically to change the louver angle
using short pulses in blinds with louvers.
Relative commands can also be parameterized for long pulses.
RUN_DOWN
Absolute command
RUN_ABS
If the blinds drive to a defined position with the help of the calculated
pulse length on outputs n or n+1
Status, MarkIDs
Position and status for the blinds and the I/O function are returned to the bus master
Various
CAL
Command to drive the blinds once all the way to the top and to the
bottom to (by measuring motor current) determine the runtime
RunTimeDownUp (calibration)
GET_MOT_POS
Position query from bus master
Normally, preparameterized outputs are used customized to the actuators to be
operated.
The following parameters are available for individual parameterization:
Parameter Description Range (default)
Increment = 0.01 s
RunTimeDownUp Runtime from Down2 to Up 1...655 s (180 s)
RunTimeUpDown Runtime from Up to Down2 1...655 s (180 s)
RunTimeDown1Down2 Runtime from Down1 to Down2 1...655 s (1.5 s)
BreakTime Break between opening a relay and closing an other
relay (change of ditection)
0.2...25.5 s (0.5 s)
EndPosDetection Detection of the end positions by measuring the motor
current on the relay outputs
Inactive, Active, Once
(Active)
MotorDelay Delay between pulse start and motor action. Some
motors take a certain time before they consume current.
This parameter prevents the current detection from
assuming that the motor is in end position or that there
is a fault.
0.01...2.55 s (0.1 s)
MotorOverTravelUp
Delay between pulse end and blinds stop (UP)
0.01...2.55 s (0.1 s)
MotorOverTravelDown
Delay between pulse end and blinds stop (DOWN)
0.01...2.55 s (0.1 s)
BackupMode Backup status in case of master down
Keep = Last

No = Relay inactive
