SERIES

Ultimate safety and security
Systems can be operated safely because the
and safety is ensured by monitoring.
Servo Drives comply with safety standards
Satisfies requirements of the SIL 3 of the IEC 61508 functional safety standards (first in Japan)
Certification will make it easier to set up systems that conform to safety standards for press machines and other
systems in Europe and other regions. Certification also helps reduce the number of hours required for wiring and of
peripheral devices. Complies with Stop Category 0 (Safe Torque Off)

New machine safety system
Monitoring
-Safety relay no longer
needed
-Less wiring required
because the monitoring
function is built inside the
SERVOPACKs.
The safety function works even for a single problem.
The safety function is enhanced with compliance with
the EN ISO 13849-1 PLe (performance level e).
Note: Although the safety performance level of the series Servo Drives is
PLd (performance level d), the benefits described in the figure on the
left apply.
Systems that need to satisfy the required performance
level e (PLr e) can easily be configured.
Protect systems from high temperatures
SERVOPACKs and Servomotors are equipped with
temperature sensors that can directly monitor temperatures
of machines and detect abnormalities to prevent failures.
Real-time temperatures can be viewed on a display by using
Machine Controllers.
