Figure A-14 Diagram 2 - acceptance for SDI-, "SDI active" becomes inactive when the motor is switched off
Procedure
To perform the acceptance test of the SDI function for the negative direction of rotation,
proceed as follows:
Status
1. The inverter is ready
Check the following:
● SDI- is not active (r9722.13 = 0).
● 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 (r9722.7 = 0).
● Record the following values: r9713[0], r9722
Display the bits r9722.0/.1/.7/.13
● Select the interval and pretrigger so you can recognize when the SDI tolerance has
been exceeded and the subsequent drive responses.
