Features - Siemens SINAMICS S120 Function Manual

4.10.2

Features

S Automatic deactivation with a DC link voltage greater than 40 V
(measurement tolerance ±16 V) with fault message F07826 and immediate
pulse inhibit (OFF2)
S Can be activated via parameter p1272
S Line contactor control can be deactivated in simulation mode
S Power semiconductors can be gated at low DC link voltages and without a
motor (for test purposes)
S Power unit and closed-loop control can be simulated without a motor being
connected
4.10.3 Commissioning
Simulation mode can be activated using p1272 = 1; the following pre-requisites
must be fulfilled:
S The drive unit must have been commissioned for the first time (default: Stan-
dard induction motors).
S The DC link voltage must be lower than 40 V (observe the tolerance of the DC
link sensing).
