Operating Parameters
The IK 220 requires operating parameters to properly execute
the desired functions. Predetermined default values are set
when downloading the supplied operating software. The default
values are shown in bold typeface in the following table. You
can change the parameter values with function IK220WritePar
(Write Parameters), and then check your changes with function
IK220ReadPar (Read Parameters).
The following parameters are available (default values in bold
typeface):
Param.

mat Meaning
1 16 bits 0: incremental encoder
1: EnDat 2.1 encoder
2: SSI encoder
2 16 bits Parameter functions only if
parameter 1 = 0

4 16 bits 0: Positive counting direction
1: Negative counting direction
5 32 bits 0 to 0xFFFFFFFF:
Signal periods/revolution
for angular axes, effective only if
