9.8 Response time of the safety functions
Response time of the safety functions of the machine
The standard EN ISO 13849-1 requires the machine safety manual to report
the response time of the safety functions implemented in the machine. These
measurements must be taken from the instant the danger condition takes
place (e.g. door opened) to the instant the safety function is executed (e.g.
machine stopped). This time will depend on the design of the machine's safety
control circuit.
Response time of the safety functions of the drive
The table below provides the response times of the safety functions of the
AXD/SPD.
Actual response time of the holding brake
Consider that the actual response time of the holding brake is the sum of the
response time of its control and the response time of the brake itself which
for FAGOR brakes varies between 5 and 30 ms.
