DANGER Failure to observe these precautions may result in serious injury.
•
Only qualified personnel are authorized to install the "safe
restart" STO (Safe Torque off) and set the parameters.
•
All control devices (switches, relays, PLC, etc.) and the
control closet must meet the requirements for EN 13849.
This consists of:
– Door switches, etc. with at least IP54 protection
– Control cabinet with at least IP54 protection
•
The proper cables and end-sleeves must be used.
•
All cables that affect safety (e.g. control cables for the
ENABLE 1 and ENABLE 2 inputs) must be laid in a cable
duct outside of the control cabinet. Short and cross cir-
cuits have to be avoided. See EN ISO 13849.
•
When using the SS1 (Safe Stop 1) safety function, the
typical turn-off delay is 0.5 seconds. Subsequent actions
that require the STO (Safe Torque Off) function (i.e. man-
ual access to the machine), can only be released after 1
second.
•
If external forces influence axes that are used with the
STO safety function (e.g. hanging load), additional
measures must be taken (such as an electromagnetic
double-surface spring brake, instead of a permanent
magnet brake).
CAUTION The main power supply for the servo amplifier must be disconnected using
the main switch for the following instances:
•
Cleaning, maintenance or repairs
•
Extended still-stand periods
