3.2 Important instructions for the Safety Function
• All control components (switches, relays, PLC, etc.) and the control
cabinet must comply with the requirements of the ISO 13849. This
includes:
– Door – switches, etc. with protection class IP54 as minimum
– Control cabinet with protection class IP54 as minimum
• For the 24 V supply use only PELV/SELV power supplies.
• Use adequate insulated wire end sleeves
• External source voltage at the inputs ENABLE_L and ENABLE_H has
to be excluded in the cabinet and outside. Make sure, that short
circuits between single cables are excluded! See also EN ISO 13849.
• All safety-relevant cables (e. g. control cable) has to be installed e. g.
in a cable duct, if pass outside the control cabinet
• The connector pin X1 / 3 is marked as “reserved” and must not be
connected externally
• If the safety function SS1 (Safe Stop 1) is used, the minimum switch-
off time is 0.4 s. Following actions which need the safety function STO
(Safe Torque off) e.g. manually engagement into the machine, must
not be released before 1 s
• When an external force is likely to act with the function ”safe restart
lock” (e.g. force to the load by hanging load) additional measures
have to be provided (e.g. double-disc spring set brake, instead of
permanent magnetic-excited brake)
Failure to observe this precaution can result in severe injury and equipment damage.
The mains supply voltage of the servo drive system has to be switched off by the main
switch in following cases.
• Taking measures for cleaning, maintenance and repair
• Taking out of service for a longer time
Failure to observe this precaution can result in severe injury and equipment damage.
