Ramp down before target
Depending on the application it may be convenient to slow down actuator speed, getting close to the target. By
setting the ‘Ramp Down Before Target’ to a different distance (default value is 20, corresponding to 2 mm) you
can control when this slow down takes place.
*IR = Input Register, HR = Holding Register
Activation of multiple actuators
In some large MODBUS communication systems the sequential and time-consuming polling of the slaves by the
master makes it hard to command multiple actuators to move at the same time. The LINAK LA35/LA36/LA37
MODBUS actuator offers a feature to improve this functionality. Below is shown the process to start 3 actuators.
*IR = Input Register, HR = Holding Register
• The steps, as described above, must be performed in the right sequence (i.e. write to HR
5 as the last step) in order to obtain the correct functional behaviour.
• The power-line (supply and cabling) has to be dimensioned for simultaneous run of all
started actuators.
1 The “Next time to run” command must be sent minimum 2 sec before the trigger (the trigger is HR4 = HR10 and HR5 = HR11)
2
When waiting for next time to run (IR 1 = 3) the function will be interrupted if a new value is written to ‘Command, Remote’ (HR 2)
Step Register * Action
1 HR 17 Write a value into ‘Ramp Down Before Target’ parameter (unit is 1/10
mm).
Step Register * Action
1 - Check that general run-prerequisites are fulfilled in all 3 actuators.
2 HR 1 Write a value into ‘Target Position’ parameter (unit is 1/10 mm relative
to offset) of each actuator.
3 HR 10, 11 Clear the internal clock by writing a 0 (or set to a desired value) into
‘Current Time (s/m)’ parameters of all actuators by use of a broadcast
request.
4 HR 4 and 5 Write the exact trigger time into ‘Next Time to Run (s/m)’ parameters of
each actuator.
5 HR 2 Write a 3
1
(Run at “Next time to run”) into ‘Command, Remote’
parameter of each actuator. The actuators are now armed to start
moving towards the target position when the specified absolute time
arises (HR 4 = HR 10 and HR 5 = HR 11).
