with adjustable current limitation (switchable via AS-i bit "speed f1/
speed f2"), with reduction of frequency if exceeded
Function descrip-
tion
The current limitation can be set via switch f2. The AS-i bit "speed f1/speed 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
• Switching via AS-i "speed f1/speed f2" between setpoint f1 and setpoint f2 is no
longer possible.
