- nearly 100% of the rotation speeds are in the range of 0 to 30.000 r.p.m.
- the number of sprockets varies (without gearing) between 1 and 100
- in automation, the frequency supply never exceeds 10 kHz (rather 3 kHz)

Parameter

Description

Applying of the measuring signal is not applicable.

Complies with 9.9999 Hz

Assumed final value

Complies with 64 sprockets

Setting up the advice

Based on the default settings of the display, the following parameters need to be changed:

Examples: Adjustment according to number of sprockets at unknown rotation speed.

Assume a rotation speed of 60 r.p.m. at 1 Hz, whereat the real frequency value will not be 
considered.

Our example complies with a number of sprockets of 64.

Parameter

Description

Applying of the measuring signal is not applicable.

Complies with 9.9999 Hz

Assumed final value

1 position after decimal point

Complies with 64 sprockets

If the frequency needs to be displayed with a position after decimal point, then a 60 has to be 
selected as final value for this adjustment.
