● Technological application:
● Motor identification:
Note
In many cases, "Motor data identification at standstill" is the correct selection for SINAMICS
G150.
"Motor data identification at standstill and when motor is running" is the recommended
setting for closed-loop speed control with encoder; this measurement is normally performed
for non-coupled machines.
When the rotating measurement is selected, the drive triggers movements in the motor that
can reach the maximum motor speed. The EMERGENCY OFF functions must be fully
operational during commissioning. To protect the machines and personnel, the relevant
safety regulations must be observed.

– "(0) Standard drive (VECTOR)"
Edge modulation is not enabled.
The dynamic voltage reserve is increased (10 V), which reduces the maximum output
voltage.
– "(1) Pumps and fans"(default setting)
Edge modulation is enabled.
The dynamic voltage reserve is reduced (2 V), which increases the maximum output
voltage.
– "(2) (Encoderless control down to f = 0 (passive loads)"
Controlled operation down to standstill is possible for passive loads.
These include applications in which the load cannot produce a regenerative torque on
startup and the motor comes to a standstill when pulses are inhibited.
– (0): Disabled
– (1): Motor data identification at standstill and when the motor is rotating
– (2): Motor data identification at standstill
– (3): Motor data identification when the motor is rotating
