11.4.2 Manual safety function check
For the functional test, check both disconnecting paths separately.
1. disconnecting path: Pulse inhibit via safety relay K
SR
How to proceed during the test:
1. Alternately apply LOW and HIGH level to input X11/34 and check the
states given in the table below.
Specification Correct status
Individual test Input relay activation (X11/34) Output feedback (X11/K31)
Pulse inhibit LOW HIGH
Pulse enable HIGH LOW
The individual tests are passed if the correct states given in the table result.
2. disconnecting path: Controller inihibit
Requirement for the test:
Æ’ "Quickstop" (QSP) function deactivated
Æ’ "Automatic DC injection brake" deactivated (C0019 = 0)
Æ’ Pulses enabled by the safety relay K
SR
(X11/34 = HIGH)
How to proceed during the test:
1. Set controller inhibit (X5/28 = LOW).
2. Define a setpoint n
set
> 0.
3. Check that the motor is not rotating.
The individual test is passed if the motor does not rotate.
Functional test not passed
If an individual test results in an impermissible status, the functional test is
not passed.
Æ’ The drive or machine has to be shut down immediately.
Æ’ Commissioning is not permitted until the safety function operates
correctly.
