The SQS-SS2 tests have been executed, possible deviations documented
and testing approved.
Notes:
3.7.5 SLS
When possible, test the SQS safety function before the SLS safety function. Do the test steps for all the
used SLS limits.
Make sure that the drive is in READY state.
Make sure that no safety functions requested.
Give a RUN request to the AC drive.
The speed should be in the safe range below the SLS limit
that is being tested.
Activate the SLS function from the desired source.
A warning should occur to indicate the SLS function
activation:
Warning: F46 SafetyRequest, subcode: SLS (6). Warning: F47
SafetyReached, subcode: SLS (6).
NOTE! The display of the warning depends on the settings
of the AC drive.
NOTE! Depending on the SLS mode, the function may be
reached after a specified time or almost immediately (once
the speed is below the limit). Once the function is reached
the “request” warning should disappear.
Increase the speed above the reached SLS limit.
The SQS function becomes active once speed exceeds the
limit and the SLS function detects the violation.
Do a check that the violation occurs at the expected speed.
Verify that the SQS function operates correctly and is
suitable for the process.
NOTE! The SQS function may be operating in the STO, SS1,
or SS2 mode.
Make sure that the motor is stopped.
