the motor from the line supply in order to be able to carry out maintenance work on the drive converter without incurring any down times.

Synchronizing is activated using parameter p3800 and either internal or external actual voltage sensing is selected. For the internal actual voltage sensing (p3800 = 1), the voltage setpoints of the electrical motor model are used for synchronizing. For the external actual voltage sensing (p3800 = 2), the voltage is sensed using a VSM, this is connected between the Motor Module and Motor. The voltage values must be transferred to the synchronization via connectors r3661 and r3662.

4.18Simulation operation

4.18.1Description

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.

Simulation mode enables you to test communication with a higher-level automation system. If the drive is also to return actual values, note that it must be switched over to sensorless operation during simulation mode. This means that large parts of the SINAMICS software
