No. Question Relevant Done
... b1) Have the inputs for STO and SBC been wired to the safety relay
unit via 2 channels? Yes o
No o
o
... b2) Have the check-back outputs STA, SBA been wired to the safety
relay unit? Yes o
No o
o
... b3) If multiple CMMT-AS have been connected together (linked) via
X1A: Have the connection instructions been taken into account?
è 4.1.5 Cross wiring of several servo drives.
Yes o
No
o
o
... c) Functional tests: Yes o
No o
o
... c1) Actuation of the system emergency stop: Is the drive brought to a
standstill in the desired manner (stop 0, stop 1, SBC)? Yes
o
No o
o
... c2) Is a restart after an emergency stop prevented in the safety relay
unit? This means that when the emergency stop button is pressed
and the enable signals are active, no movement occurs in response
to a start command until acknowledgement has taken place via the
“Restart” input. Yes o
No o
o
... c3) Actuation of the safety sub-function STO. If only one of the
assigned inputs #STO-A or #STO-B is activated: Is the safety sub-func-
tion STO executed immediately? Does the STA output remain at the
low level? Is the error “Discrepancy time violation” logged in the
CMMT-AS once the discrepancy time has elapsed? Yes
o
No
o
o
... c4) Actuation of the safety sub-function SBC. If only one of the
assigned inputs #SBC-A or #SBC-B is activated: Is the assigned safety
sub-function executed immediately? Does the SBA output remain at
the low level? Is the error “Discrepancy time violation” logged in the
CMMT-AS once the discrepancy time has elapsed? Yes
o
No o
o
... c5) Does the safety relay unit detect a fault if SBA/STA do not switch
to the high level when the safety sub-function is requested via 1
channel? Yes o
No o
o
... c6) Only when linking multiple CMMT-AS and connecting the diag-
nostic outputs: Does the safety relay unit detect a fault if the SBA/STA
linkage is interrupted at a particular point and the corresponding
diagnostic output does not switch to the high level on one CMMT-AS
when the safety sub-function is requested via 1 channel? Yes
o
No o
