SSR

When possible, test the SQS safety function before the SSR safety function. Do the test steps for all the
used SSR 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 between the SSR
limit(s).
3 Activate the SSR function from the desired source.
4 A warning should occur to indicate the SSR function
activation:
Warning: F46 SafetyRequest, subcode: SSR (5).
Warning: F47 SafetyReached, subcode: SSR (5).
NOTE! The display of the warning depends on the settings
of the AC drive.
NOTE! Depending on SSR parameter values, the function
may be reached after a delay. Once the function is Reached,
the "request" warning should disappear.
5 Increase the speed above the SSR limit.
6 The SQS function becomes active once speed exceeds the
limit and the SSR 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.
Applicable faults are shown:
Warning: F47 SafetyReached, subcode: SQS (4).
Warning: F48 SafetyViolat, Safety function: SSR, subcode:
7/8 (depending on the violated limit).
