Siemens SINAMICS G130 Operating Instructions Manual page 157

– "(4) Dynamic response in the field-weakening range"
– "(5) Start-up with high break loose torque"
– "(6) High load inertia"
● Motor identification:
– (0): Disabled
– (1): Identifying motor data and optimizing the closed-loop speed control
– (2): Identifying motor data (at standstill)
– (3): Optimizing closed-loop speed control (when rotating)
Note
Identifying motor data at standstill
In many cases, "Motor data identification at standstill" is the correct selection for SINAMICS
G130.
"Identify motor data and optimize speed control" is the recommended setting for closed-loop
speed control with encoder; this measurement is normally performed with a motor that is not
coupled to a load.
Danger to life if the motor unexpectedly moves during motor identification in the rotating
mode
When selecting motor identification with optimization in the rotating mode, after
commissioning, the drive initiates that the motor rotates with speeds that can reach the
maximum motor speed.
• Observe the general safety instructions.
• Ensure that the EMERGENCY STOP functions are fully functional when commissioning

Space vector modulation with overmodulation is enabled.
The dynamic voltage reserve is increased (30 V), which reduces the maximum output
voltage.
This selection is suitable for speed-controlled start-up with sensorless vector control.
Start-up current permanent and is increased upon accelerating.
Suitable for high load inertia with/without gearbox coupling.
The acceleration model is activated, the acceleration control is 100%.
