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).
Assignment of the setpoint/actual value channels
For each machine axis to which a drive is assigned,
• a setpoint channel and
• at least one actual-value channel
must be parameterized.
A second actual-value channel can be set up as an option.
Notice
The motor measuring system is always used for the speed control function. Motor and motor
measuring system must therefore always be connected to the same drive module.
