The converter is ready
• The converter signals neither faults nor alarms of the safety functions
(r0945[0...7], r2122[0...7]).
• STO is not active (r9773.1 = 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.
Test each configured activation, e.g. via digital inputs and PROFIsafe.
3.2. Check the following:
When controlled via PROFIsafe
• The converter 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 converter signals neither faults nor alarms of the safety functions
(r0945[0...7], r2122[0...7]).
• The converter 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 converter signals neither faults nor alarms of the safety functions
(r0945[0...7], r2122[0...7]).
A.2 Acceptance tests for the safety functions
