Indication on display
Description/cause
Remedy
Incorrect phase seq
The phase conductors L1, L2 and
L3 are connected in the wrong
sequence.
Only applicable if connected to a
3-ph AC system
Correct the sequence of the
phase conductors L1, L2 and L3
by exchanging two phases.
Mains quality
Due to insufficient mains quality,
the controls cannot detect the
phase sequence (sequence of
phase conductors L1, L2 and L3)
within the pre-set time frame
provided for monitoring.
Check mains voltage.
For 3-phase/1-phase AC current,
the permissible variation of the
mains voltage is ±10% (option
±30%). The permissible variation
of the mains voltage is ±5%
Check parameter Tripping time
M0172, extend timeframe if
required.
Thermal fault
Motor protection tripped
● Cool down, wait.
● If the fault indication display
persists after cooling down:
- Set selector switch to
position Local control
(LOCAL) and reset fault
indication using the RESET
push button.
● Check fuses.
Fault no reaction
No actuator reaction to operation
commands within the set reaction
time.
Check movement at actuator.

Syn. link deviation
Synchronous link function: Actual
position values of master actuator
and slave actuator are not
synchronous (excessive
deviation).

parameter.
Syn. link NotReady
Synchronous link function: Slave
actuator is not ready.
Check Deviation MA/SA [%]
parameter.
