9.7 Response time
FAGOR recommends measuring the response time of the implemented
safety functions. This measurement 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.
The following table shows delay data related to both channels in the indi-
cated conditions.

Delay data.
Delay
Comment
Internal channel
(AXD/SPD drive)
< 15 ms
Measurement taken in a circuit equiva-
lent to that of figure
with a safety
relay for emergency stop from Telemeca-
nique
TM
. The delay of the internal circuit is
less than 15 ms.
External channel
(main contactor)
Depends
on used
- KM1
contactor
Measurement taken with a Schneider
TM
contactor. The delay of the DDS system
between the actual opening of the con-
tacts and the “Torque Off” is less than 35
ms.
