Siemens SINAMICS G120C Function Manual

Status
3. Select STO
3.1. Select STO while the motor is running.
Test each configured activation, e.g. via digital inputs and PROFIsafe.
3.2. Check the following:
When controlled via
PROFIsafe
When controlled via a fail-
safe F-DI digital input
When controlled via
STO_A and STO_B ter‐
minals on a PM240‑2 or
PM240P‑2 Power Mod‐
ule
● The inverter signals
the following:
"STO selection via
PROFIsafe"
(r9772.20 = 1)
● The inverter signals
the following:
"STO Selection via
terminal"
(r9772.17 = 1)
● The inverter signals
the following:
"STO Selection via
terminal on Power
Module"
(r9772.25 = 1)
● If a mechanical brake is not available, the motor coasts down.
A mechanical brake brakes the motor and holds it to ensure that it remains
at standstill.
● The inverter signals neither faults nor alarms of the safety functions
(r0945[0…7], r2122[0…7]).
● The inverter signals the following:
"STO is selected" (r9773.0 = 1).
"STO is active" (r9773.1 = 1).
4. Deselect STO
4.1. Deselect STO.
4.2. Check the following:
● STO is not active (r9773.1 = 0).
● The inverter signals neither faults nor alarms of the safety functions
(r0945[0…7], r2122[0…7]).
You have performed the acceptance test of the STO function.
