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
● The inverter signals
the following:
"STO selection via
PROFIsafe"
(r9772.20 = 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).
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]).
When controlled via a fail-
safe F-DI digital input
● The inverter signals
the following:
"STO Selection via
terminal"
(r9772.17 = 1)

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
terminal on Power
Module"
(r9772.25 = 1)
