Output monitoring
(Output monitoring)
S P
0 ... 3
{ 0 }
This protective function monitors the output current at the U-V-W terminals
plausibility. In cases of error, the error message E016 is output.
0 = Disabled: Monitoring is not active.
1 = Only motor phases: The output current is measured and checked for symmetry. If an
imbalance is present, the FI switches off and outputs the error message E016.
2 = Only magnetisation: At the moment the FI is switched on, the level of the excitation
current (field current) is checked. If insufficient excitation current is present, the FI switches
off with the error message E016. A motor brake is not released in this phase.
3 = Motor phase + Magnet: Monitoring of the motor phases and magnetisation as in 1 and 2
are combined.
NOTE:
This function can be used as an additional protective function for lifting applications,
but is not permissible on its own as protection for persons.

Mode phase sequence
(Rotation direction mode)
S P
0 ... 7
{ 0 }
For safety reasons this parameter can be used to prevent a rotation direction reversal and
therefore the incorrect rotation direction.
This function does not operate with active position control (SK 53xE and above, P600 ≠ 0).
0 = No restriction, no restriction of the direction of rotation
1 = Dir. key disabled, the direction key of the ControlBox SK TU3-CTR is disabled.
2 = CW only*, only clockwise direction is possible. The selection of the "incorrect" rotation
direction leads to the output of the minimum frequency P104 with the field of rotation R.
3 = CCW only*, only counter-clockwise direction is possible. The selection of the "incorrect"
rotation direction leads to the output of the minimum frequency P104 with the field of
rotation L.
4 = Enable direction only, rotation direction is only possible according to the enable signal,
otherwise 0Hz.
5 = CW only monitored *, only the clockwise direction is monitored, only a clockwise field
rotation is possible. The selection of the "incorrect" rotation direction leads to the FI
switching off (control block).
If necessary, an adequately large setpoint value (>f
min
) must be observed.
6 = CCW only monitored: *, only the counter-clockwise direction is monitored, only a counter-
clockwise field rotation is possible. The selection of the "incorrect" rotation direction
leads to the FI switching off (control block). If necessary, an adequately large setpoint
value (>f
min
) must be observed.
7 = Only enabled direction monitored, only the enabled direction is monitored, rotation is only
possible according to the enable signal, otherwise the FI is switched off.
*) Applies to keyboard (SK TU3-) and control terminal actuation, in addition, the direction key on
the ControlBox is blocked.
