Setpoint/Actual Value Channels - Siemens SINUMERIK 840Di sl Commissioning Manual

ADI4
Because a ADI4 module does not support acyclic communication on the PROFIBUS, we
recommend entering value 4 as the drive type for any drive operated via ADI4:
● MD13080 $MN_DRIVE_TYP_DP[n] = 4

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 $MA_CTRLOUT_TYPE (output type of setpoint value) = 0
• MD30240 $MA_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.
The following machine data 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):
MD30350 $MA_SIMU_AX_VDI_OUTPUT (output of axis signals with simulation axes)
Assignment of the setpoint/actual value channels
The following parameters must be defined for each machine axis that a drive is to be
assigned to:
● a setpoint channel and
● at least one actual-value channel
A second actual-value channel can be set up as an option.

We recommend entering drive type 4 manually for drives connected via ADI4:
