The signal frequency at the selected repetition frequency input can be scaled via the
parameter Divider 497. The parameter figure is comparable with the division marks
of a speed sensor per rotation of the drive mechanism. The frequency limit of the
parameterized digital input is to be taken into account for the frequency of the input
signal.

497 Divider 1 8192 1024
Note: The reference value specification within the different functions enables the
use of the repetition frequency signal as a percentage figure. A signal fre-
quency 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.

Value PWM
Set the reference value via one the following modes.
− For reference frequency values:
Reference Frequency Source
475 = “32 - Rep. Frequency Input (F3)”. The
PWM-value is related to
Maximum Frequency
419.
− For reference percentage values:
Reference Percentage Source
476 = “32 - Rep. Frequency Input (F3)”. The
PWM-value is related to
Maximum Reference Percentage
519.
Parameter
PWM-Input
258 shows the actual value of the PWM input.
