with adjustable current limitation (switchable via terminal f1/f2), with
reduction of frequency if exceeded
Function descrip-
tion
The current limitation can be set via switch f2. The binary input terminal f1/f2 can be
used to toggle between maximum current limit and the current limitation set via switch f2.
Response after
reaching the cur-
rent limitation
• After reaching the current limit, the unit reduces the frequency using the current lim-
itation function and if necessary stops the ramp to prevent the current from increas-
ing.
• If the unit operates at the current limitation, the status is displayed through rapid
green flashing of the status LED.
In-system values
for setpoint f2/mini-
mum frequency
• It is no longer possible to toggle via terminals between setpoint f1 and setpoint f2 in
terminal operation or to set the minimum frequency in bus operation.
• The minimum frequency in bus operation is fixed at 2 Hz.
