Hints for operation
1. Set duration of each pause and for operation into OPEN and CLOSE directions individually
(from 0 to 6553 s),refer also to „Changing parameter values/characteristics“ on page 24.
2. Switch on test operation, select ‘On’ in the ‘Test operation’ menu and switch actuator to RE-
MOTE mode. Changing over to LOCAL mode will stop the test operation.
If test operation is switched on and off again, the cycle will be continued from the step the test was
stopped.
Operation in the LOCAL mode via Drive Controller is not detected by the cycle. If the actuator has
ready reached the end position when changing over to REMOTE mode, the remaining run time and
thefollowingpausersthavetoexpirebeforetheactuatorstartstomoveagain.
Should the actuator reach the end position before the set operation time has elapsed, it will switch
off.
8�6�14 DC link voltage limitation
Some torque peaks exceeding the voltage tolerance (+15 %), can cause charging of the DC link
during standstill.
This is avoided if the parameter (DC link voltage limitation = on) is active.

8�6�13 Test operation
With this function, the actuator is switched to a
continuous duty in REMOTE mode, by continu-
ously repeating a cycle with the following steps:
Operation into CLOSE direction – pause– opera-
tion into OPEN direction – pause – operation
into CLOSE direction etc. The duration of each
step can be individually set from 0 to 6553 s.
The number of cycles can be completed can be
read via the ‘Diagnosis’ - ‘Operation data actua-
tor’ - ‘switching cycles’. In this case, a switching
cycle corresponds to a cycle.
Prerequisites: The actuator must be ready for
operation, i.e. end position, speed, cut-off mode
and tripping torques are set.
