Figure A-5 Diagram 2 - acceptance test for SS1 with acceleration monitoring
Procedure
To perform the acceptance test of the SS1 function, proceed as follows:
Status
1. The inverter is ready
● The inverter signals neither faults nor alarms of the safety functions
(r0945[0…7], r2122[0…7]).
● SS1 is not active (r9722.1 = 0).
Go online with the STARTER and configure the following trace:
● Trigger on variable - bit pattern (r9720.1 = 0)
● Record the following values: r9714[0], r9714[1], r9722
Display the bits r9722.0/.1
● Select the time interval and pretrigger so you can recognize the selection
of SS1 and the transition into the subsequent STO state.
● Start the trace.
2. 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.
