Figure A-10 Diagram 2 - acceptance test SSM with inactive feedback signal when the motor is switched off
Procedure
To perform the acceptance test of the SSM function, proceed as follows:
Status
1. The inverter is ready
● Check: The inverter signals neither faults nor alarms of the safety functions (r0945[0…
7], r2122[0…7]).
Go online with the STARTER and configure the following trace:
● Trigger on variable - bit pattern (r9722.15 = 0)
● Record the following values: r0899, r9714[0], r9722
Display the following bits:
– r0899.11
– r9722.15
● Select the interval and pretrigger so you can recognize when the level exceeds the
SSM limit and subsequently falls below it again.
