Fixed frequency FF1 to FF4 selection
With the digital inputs configured as FF1 to FF4 you can select up
to 16 user-definable fixed frequencies (including frequency
setpoints), depending on which of the inputs is active or inactive
(a Table 13). It is not necessary to use all the fixed frequency
selection inputs at the same time. Using only three inputs, for
example, allows you to choose between eight fixed frequencies;
with two fixed frequency selection inputs, four fixed frequencies
are available for selection.
The fixed frequencies have a higher priority than all other setpoint
values and can be accessed at any time through inputs FF1 to FF4
without needing to be enabled separately. Jog mode, to which the
highest priority is assigned, is the only operation with a higher
priority than the fixed frequencies.
Table 13: Fixed frequencies
X Program one or more of the digital inputs 1 to 5 as FF1 to FF4,
by entering the values 02 (FF1) to 05 (FF4) under the correspon-
ding PNU (C01 to C05).
The fixed frequencies can be programmed in two ways:
• input of the fixed frequencies under PNU A21 to A35,
• input of the fixed frequencies under PNU F01.
With PNU F01, it is possible to modify the parameter even though
the parameter protection PNU b31 is set (a Page 66).
Input of the fixed frequencies under PNU A21 to 35
X Goto PNU A21 and press the PRG key.
X Use the arrow keys to enter the fixed frequency and confirm
with the ENTER key.
X Repeat these steps for PNU A22 to A35 to suit your required
frequencies.
Input of the fixed frequency under PNU F01
For frequency input under PNU F01, the value 02 must be set
beforehand in PNU A01.
X To select a fixed frequency stage, activate the digital inputs as
listed in Table 13.
X Goto PNU F01.
The current frequency appears on the display.
X Use the arrow keys to enter the fixed frequency and confirm
with the ENTER key.
The entered value is saved in the parameter which you have
selected with the digital inputs (a Table 13).
X Repeat these steps for your additional fixed frequencies.
