4.23 Simulation mode
4.23.1 Description
Simulation mode allows you to simulate the drive without a connected motor and without the
DC link voltage. In this case, it should be noted that the simulation mode can only be
activated under an actual DC link voltage of 40 V. If the voltage is higher, simulation mode is
reset and fault message F07826 is output.
With the simulation mode, you can test the communication with a higher-level automation
system. If the drive is also to return actual values, note that it must be switched over to
encoderless operation during simulation mode. This means that large parts of the SINAMICS
software (e.g., software channel, sequence control, communications, technology function,
etc.) can be tested in advance without requiring a motor.
For units with outputs of > 75 W it is recommended to test the activation of the power
semiconductors after repairs. To do so, a DC voltage < 40 V is applied to the DC link, and
the possible pulse patterns must be tested by the control software.
The software must allow enabling of the pulses and the output of various frequencies. IThis
is implemented using V/f control or encoderless closed-loop speed control.
Note
Simulation mode cannot be activated without a power unit. A power unit must be connected
via DRIVE-CLiQ.
