⇒ Select the required data:
● Technological application:
– "Standard drive (VECTOR) (0)"(default setting)
Edge modulation is not enabled.
The dynamic voltage reserve is increased (10 V), which reduces the maximum output
voltage.
– "Pumps and fans (1)"
Edge modulation is enabled.
The dynamic voltage reserve is reduced (2 V), which increases the maximum output
voltage.
– "Passive loads (for sensorless control down to f = 0) (2)"
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.
● Motor identification:
"Motor data identification with motor running" is normally the appropriate default setting
for SINAMICS S150, especially if an encoder is used for speed control.
