Assigning the actual value channels
The 1st measuring system (Index 0) of the machine axis on the measuring input
of the SIMODRIVE 611U drive module is assigned via the axis–specifiec ma-
chine data:
S
MD 30220: ENC_MODUL_NR[0] = 1
where 1 = (Index 0 of the relevant MD13050 + 1)
The 2nd measuring system (Index 1) of the machine axis on the measuring cir-
cuit input of the ADI4 module is assigned via the axis–specific machine data:
S
MD 30220: ENC_MODUL_NR[1] = 4
where 4 = (Index 3 of the relevant MD13050 + 1)
Also refer to Subsection 10.5.4, Page 10-315.
