Before using the profile torque mode, set the drive to position mode (Pn000.X=2) and select the position command source
as Canopen given (Pn400.X=5). The following table shows the operating procedure for the profile speed mode.

11.2.7.4 Home position return mode (hm)
The home position return mode is used to find the mechanical home and locate the position relationship of the mechanical
home to the mechanical zero point.
Mechanical home position: a fixed position on the machine that corresponds to a defined home signal switch.
Mechanical Home = Mechanical Zero + 607C (Home Offset)
Mechanical zero point: the absolute 0 position mechanically.
After the servo drive has finished returning to the home point, the motor will stop at the mechanical home point and the
