Operation with fixed frequencies
Configuration of the parameters
Method of operation
Inputs 1 and 2 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 acti-
vated, 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, see
Section ”Fixed frequency FF1 to FF4 selection”, Page 56.
The circuit example also includes the parameter definition for one
output signal each on terminals 11 and 12. The type of output
signal is configured with PNU C21 for digital output 11 and with
C22 for digital output 12.
