Operation with fixed frequencies
Configuration of the parameters
Method of operation
Inputs FW and 5 function exactly as described in the first example.
With the activation of one or both fixed frequency inputs FF1 and
FF2, the current frequency setpoint applied to the motor is
replaced by the fixed frequency determined by FF1 and FF2, and
the motor brakes or accelerates according to the fixed frequency
applied. If neither of the fixed frequency inputs FF1 and FF2 is
activated, the frequency setpoint is determined through analog
inputs O (voltage setpoint value) or OI (current setpoint value). The
wiring for these terminals is not shown in this circuit example. For
the combination of the individual fixed frequency values,
a section “Fixed frequency selection (FF1 to FF4)”, page 68.
The circuit example also contains the parameter settings for one
output signal each at terminals K23-K24 and K33-K34. The output
signal type is configured with PNU C021 for relay output K23-K24
and with PNU C022 for relay output K33-K34.
