9.1.3 Configure/parameter ise encoder emulation
The following settings can be configured and parameterised in the Festo Configuration Tool (FCT):

Description
Encoder Data
Number of Increments Value, number of inc rements per revolution ( 360°).
The number of increments specifies the number of emulated incre-
mental signals “A/#A/B/#B” per revolution.
Options
Ignore Zero Pulse The zero pulse signals “N/#N” are not passed on to the slave device.
Reversal of Rotation Direc-
tion
The phase displacement of the signals “A/#A” and “B/#B” is rotat ed
by 180°.
Tab. 9.1 Configure/parameterise encoder emulation
To avoid rounding errors, the number of lines per revolution should contain the factor 2
n
.
(1,2,4,8,...2048).
