Setpoint/actual value channels

Introduction
The following points must be observed for setpoint/actual value channels:
Note
In order to guarantee that the control runs up reliably, all machine axes are declared as
simulation axes (without hardware).
• MD30130 CTRLOUT_TYPE (output type of setpoint value) = 0
• MD30240 ENC_TYPE (actual value acquisition mode) = 0
Traversing of the axes in servo mode is simulated without speed setpoint output, and no
hardware-specific alarms are output.
Machine data
• MD30350 SIMU_AX_VDI_OUTPUT (output of axis signals with simulation axes)
can be used to select whether the interface signals of a simulation axis are output at the PLC
interface (e.g. during program test, if there is no drive hardware, used in FC18 in PLC).
