18 • VACON
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.
Step
1
Make sure that the drive is in READY state.
Make sure that no safety functions requested.
2
Give a RUN request to the AC drive.
The speed should be in the safe range below the SLS limit
that is being tested.
3
Activate the SLS function from the desired source.
4
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.
5
Increase the speed above the reached SLS limit.
6
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.
7
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.
8
Make sure that the motor is stopped.
