8.5 Acceptance Test

WARNING
COMMISSIONING TEST REQUIRED
A commissioning test must be performed after installation
of the safe stop function and after every change to the
installed function. Successful completion of an acceptance
test is obligatory for compliance with Category 3 PL d
(EN ISO 13849-1).
1. Use the external safety device to disconnect the
24 V DC supply voltage from the STO terminal
while the servomotor is being driven (i.e. the
mains supply remains intact). The test step is
passed if the motor responds by coasting and the
power-off brake (if present) is applied. The drive
sends the emergency message over the CAN bus.
2. Send a Reset message over the CAN bus to the
servo drive and restart the servo drive. The test
step is passed if the servomotor remains in safe
8 8
stop and the holding brake (if present) remains
applied. The servo drive sends the emergency
message again.
3. Reapply 24 V DC to the STO terminal. The test
step is passed if the servomotor remains in coast
mode and the holding brake (if present) remains
applied.
4. Send a Reset message over the CAN bus to the
servo drive and restart the servo drive. The test
step is passed if the servomotor starts up again.
The acceptance test is passed if all 4 test steps have been
completed successfully.
