Acceptance test for STO (Extended functions)
The inverter is ready
● The inverter signals neither faults nor alarms of the safety functions (r0945[0...
7], r2122[0...7]).
● STO is not active (r9722.0 = 0).
Switch on motor
2.1. Enter a speed setpoint ≠ 0.
2.2. Switch on the motor (ON command).
2.3. Check that the correct motor is running.
Select STO
3.1. Select STO while the motor is running.
3.2. Check the following:
● 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 a 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 active" (r9722.0 = 1).
