Attention! In configurations 210, 211 and 230, digital input S4IND is by default set
for the evaluation of a speed sensor signal (track B).
If an operation mode without sign is selected (
Operation Mode 11 or
Operation Mode 12), this input is not set for the evaluation of a speed
sensor signal and can be used for other functions.
9.4.2 Division marks, speed sensor 1
The number of increments of the connected speed sensor can be adjusted via parame-

Division marks, speed sensor 1 491. Select the division marks of the speed 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 S
min
of the incremental encoder for a required minimum speed n
min
can be calculated from
this requirement.
