12/16 Operating Instructions ACU 167
If a digital input is configured as a PWM or repetition frequency input, this input
cannot be used for other functions.
Check the link of the digital inputs to other functions.
The signal frequency at the selected repetition frequency input can be scaled via the parameter
Divider
497 . The parameter value can be compared to the number of division marks of an encoder
per rotation of the drive. The frequency limit of the parameterized digital input is to be taken into
account for the frequency of the input signal.

The reference value specification within the different functions enables the use of the
repetition frequency signal as a percentage figure. A signal frequency of 100 Hz at the
repetition frequency input corresponds to 100%, 1 Hz corresponds to 1%. The
parameter
Divider
497 is to be used in a way comparable with the speed sensor
simulation.

For definition of reference values, the following settings are possible:
 For reference frequencies:
Reference Frequency Source
475 = “32 - Abs. value/PWM Inp. (F3)”. The PWM-value for
the signal is referred to
Maximum Frequency
419 .
 For reference percentages:
Reference Percentage Source
476 = “32 - Abs. value/PWM Inp. (F3)”. The PWM-value for
the signal is referred to
Maximum Reference Percentage
519 .
The actual value of the PWM input is shown in parameter
PWM-Input
258 .
