<div class="markdown_content"><p>Hi Artur,</p> <p>as mentioned by imdatatas, homing when not enabled is not supported in SoftMotion.</p> <p>If enabling before homing is not an option, an alternative might be controller based homing using MC_SetPosition.</p> <p>Best regards,</p> <p>Georg</p></div>

<div class="markdown_content"><p>So we pay 380€ for SoftMotion licenses for each robot, but have to implement such an obvious use case manually without any hint in the official documentation how to achieve this. This is crazy...</p></div>

<div class="markdown_content"><p>This is a homing routine which is controlled by setting mode of operation and started by setting a bit in the control word.</p> <p>If MC_Home is not usable for this homing method then I need to implement the same functionality. But how?</p></div>

<div class="markdown_content"><p>Hello,</p> <p>As far as I know, no matter which home mode is selected, the axis must be in Standstill mode to run MC_Home according to PLCopen state machine. <br/> However, if the function you want can already be done from a parameter in the driver of the vendor you are using, you can try to perform the same function by sending the required value to that parameter via communication with the SDO write command.</p> <p>Regards,<br/> Imdat</p></div>

<div class="markdown_content"><p>Is it possible to use MC_Home without enabling the drive (MC_Power)?</p> <p>On the drive the homing method 35 (Homing on current position) has to be executed. The drive has to stay disabled due to safety. This is explicitly allowed by the drive.</p> <p>Unfortunately MC_Home reports the error SMC_REGULATOR_OR_START_NOT_SET when executed.</p> <p>Are there other options to start homing, if not with MC_Home?</p></div>
