Division Marks, Speed Sensor 1 - BONFIGLIOLI ACTIVE Cube ACU 201-01 Operating Instructions Manual

In configurations 210, 211 and 230, digital input S4IND is by default set for the evalu-
ation of a speed sensor signal (track B).
If an operation mode without sign is selected (
12), this input is not set for the evaluation of a speed sensor signal and can be
Mode
used for other functions.

10.4.2 Division marks, speed sensor 1

The number of increments of the connected speed sensor can be adjusted via pa-
rameter
sensor according to the speed range of the application.
The maximum number of division marks S

To guarantee true running of the drive, an encoder signal must be evaluated at least
every 2 ms (signal frequency f = 500 Hz). The minimum number of division marks
