Specifying reference frequencies
The setpoint frequency can be assigned in one of three ways,
depending on the setting under PNU A01:
• through the LCD keypad’s potentiometer;
• through analog inputs O (0 to +10 V H) and/or OI (4 to 20 mA
H);
• through digital channels (PNU F001, fixed frequency CF1 to
CF15 or Modbus).
The reference source is selected with PNU A001.

h
Fixed frequency stage 0 (none of the inputs CF1 to CF4 are
activated) corresponds to the frequency setpoint
value.Depending on the value entered in PNU A001, this
can be defined with the installed potentiometer, the
setpoint value inputs O, O2 and/or OI or through
PNU F001 and PNU A020.
h
If one or more of the fixed frequencies exceeds 50 Hz, you
must first increase the maximum frequency with
PNU A004 (a section “End frequency”, page 66).
