462 Verification and validation
7. Make sure that drive parameters 92.1, 92.2, 92.10,92.17, 91.11 and 91.12 match
with the safety configuration of the FSO module (safety settings view) and that
these parameters are locked by the FSO module in the drive parameter view.
8. Make sure that you can run and stop the motor freely.
9. Start the drive to the motor speed typical for the application.
10. To confirm via the FSO module auto-diagnostics that the pulse count ( 92.10 ) is
correct, it is necessary to do the encoder commissioning test so that the encoder
does 11 full rotations. The FSO module requires 11 z-pulses to verify the pulse
count of the safety encoder.
If this is not possible, use this alternative method:
Compare the speed estimation of the drive and measured speed from the
encoder to make sure that the installation is correct, and the measurement shows
correct speed value. Monitor the following actual values of the drive and FSO
module:
11. Make sure that the encoder rotation direction is correct. See the parameters in the
previous step. If it is not correct, exchange one differential pair in the cabling.
If you have configured S_ENCGEN.11 FSE diagnostic failure reaction to be STO or
No STO , follow the steps below:
12. Make sure that system is safe for the coast stop test (follows).
13. a) If you have configured FSE diagnostic failure reaction ( S_ENCGEN.11 ) to be
STO :
1. Cause an encoder failure by disconnecting the one encoder signal channel
wire from the FSE module.
2. Make sure the FSO module goes into the Fail-safe state, FSO general fault
( 7A8B ) and FSO communication fault ( A7D5 ) are indicated in the event log,
the STO function of the drive is activated, and the drive trips for the encoder
failure.
