Commissioning
3.13 Commissioning of SIMOTICS L-1FN3 linear motors
Recording the phase voltage and the pole position angle using the STARTER trace function
An oscilloscope is not used for this technique. You do not need to disconnect the motor.
However, this technique is less accurate, as the motor voltages are not directly measured,
but calculated from the transistor turn-on duration. This technique is not permitted for
parallel-connected motors, see Chapter "Special case parallel connection (Page 218)".
1. Set the following parameters:
Image 3-62 Assignment of trace channels to check the angular commutation offset
The drive is operated force-controlled. The following parameterization is required:
2. Set p0640 = 0, to limit the motor current to 0.
3. Set p1545 = 1, to activate the travel to fixed stop.
