5 Configuration
Current limiting
No
No current limiting
Yes
The current limiting is implemented via phase angle control. In
this case, the load current is monitored on the basis of the set
current limit value and only the phase control angles that do
cause the current limit value to be exceeded are permitted.
If burst-firing mode is set, the current limiting only operates
during the soft start that is realized via a time-limited phase
angle control.
It is also possible to activate an external current limit value
via a binary input.
v Chapter 5.1.6 "Binary inputs"
Current limit value
10 % to max. load
current +10 % of the
device type
Varies depending on the device type.
For 20 A power controllers, 2 to 22 A can be set.
Resistance limita-
tion
Note:
Resistance limitation is only possible in the case
of power
controllers with integrated subordinate control loop P (code
001 in the
order code
).
No
No limitation through load resistance
Yes
The load resistance is monitored to ensure the set resistance
limit value is not exceeded.
For phase angle control, the limitation is implemented through
the phase control angle
α
.
For burst-firing mode, the limitation is implemented through
the ON/OFF ratio of the sine waves.
v Chapter 6.6 "Resistance limitation (R control)"
Resistance limit
value
0 to 999.99
Ω
If the load resistance is greater than this value,
limitation is implemented through phase angle control or limi-
tation of the switched sine waves.
Load type resis-
tance limitation
Note:
This parameter only appears in the phase angle control oper-
ating mode.
Resistive load
This setting is to be used for purely resistive load.
Transformer load
This setting is only to be used for a resistive load via a trans-
former.
Dual energy man-
agement
Switched off
This parameter only appears with the following settings:
Cycle time: fixed (500 ms),
Operating mode: burst-firing mode.
This setting allows 2 devices to be configured in such a way
that they do not simultaneously draw power from the power
supply at small output levels.
This prevents current peaks.
