Technology instructions
10.3 Motion control
Mode 1: "Simulate drive and encoder":
● In this mode, the axis in your program executes and works on a PLC without real
connected hardware regarding a PROFIdrive drive and sensor.
● You do not require the logical I/O addresses in the Technology Objects data block
(TODB). This means that you do not have to configure the sensor and drive configuration
and additional digital signals (hardware limit switches and reference point switches) in the
TO and in hardware configuration. The axis does not supply data to the logical addresses
of sensor and drive.
● Simulates TODB ActualSpeed.
● Does not use the PROFIdrive telegram in the case of PROFIdrive.
● In the case of PROFIdrive, the PLC shows a diagnostic error that the configured
hardware (peripheral devices or drives) is missing, but this has no influence on the
applicability of the axis.
● Creates homing reports in all homing modes directly. Sets positions and status,
accordingly. Does not detect hardware inputs.
● All connections can be empty.
● Axis Control Panel \ Tuning Panel works as usual.
● Supports Speed Controlled axis.
● Does not support a virtual axis (like defined by SMC); however, you can use a simulated
axis with no hardware connections like a virtual axis.
Download case:
You can download the axis with changed simulation mode during PLC in RUN. In this case,
the PLC sets the StatusBit RestartRequired". After restart of the axis, the PLC transfers the
changes to the working memory. The following table shows all axis parameters that are
connected to hardware configuration (Actor, Sensor, and PositionLimits) and required or
optional for simulation:
Actor.Interface.AddressIn
Actor.Interface.AddressOut
Actor.Interface.EnableDriveOutput
Actor.Interface.DriveReadyInput
Sensor.Interface.AddressIn
Sensor.Interface.AddressOut
Sensor.ActiveHoming.DigitalInputAddress
Sensor.PassiveHoming.DigitalInputAddress
PositionLimits_HW.MinSwitchAddress
PositionLimits_HW.MaxSwitchAddress
