Procedure
To perform the acceptance test of the SDI function for the negative direction of rotation,
proceed as follows:

Function Manual, 04/2014, FW V4.7, A5E34261271B AA
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 time interval and pretrigger so you can recognize when the SDI tolerance
•
has been exceeded and the subsequent drive responses.
Switch on motor
2.1. Enter a negative speed setpoint.
2.2. Select SDI- so that only negative speeds are permitted.
The next steps depend on what settings you made for SDI during
2.3.
commissioning:
First diagram:
The "SDI active" feedback signal
remains active when the motor is
switched off.
Switch on motor within 5 seconds after
deselecting SDI (ON command).
If you wait longer than 5 seconds for
the ON command, then STO is
activated. In this case, deselect SDI
and then select it again.
2.4. Check that the correct motor is rotating in the expected direction.
Deactivate the setpoint limitation for the acceptance test
Activate the Acceptance mode:
A.1 Examples of acceptance tests
Second diagram:
The "SDI active" feedback signal
becomes inactive when the motor is
switched off.
Switch on the motor (ON command).
