Festo – GDCP-CMMP-M3-FW-EN – 1203NH
Parameter
Description
Number of lines
The line count corresponds to the number of full periods in a track
per revolution. (Value must be between 1 and 2
28
). The increment-
al input always uses four-fold evaluation. Accordingly the resolu-
tion is higher than the line count itself by a factor of 4.
Tab. 6.14 Increment generator input parameter
The line count can normally be found in a data sheet or the name plate for the shaft en-
coder. Observe that specification of the line count is dependent on the track signals.
A/B-(N):
–
A/B (quadrature evaluation): The line count of the master is entered with reference to
one revolution.
–
Index track: If the index track is used, the specified line count must correspond to the
number of lines between index pulses.
CLK/DIR (pulse/direction):
–
The number of increments for the master referred to 90° must be entered here due to
the controller's four-fold evaluation method.
CW/CCW (upward/downward counter):
–
The number of increments for the master referred to 90° must be entered here due to
the controller's four-fold evaluation method.
After a change of the encoder data, you must save the data following download and per-
form a restart with interruption of the power supply.
