•
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 cabinet
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_L and
ENABLE_H inputs) must be laid in a conduit outside of the control
cabinet.
Short or crossed circuits in the signal lines must be avoided! See EN
ISO 13849
•
The terminal connections X3/Pin 2, Pin 4, Pin 10 and Pin 12 are labelled
as
“reserved” and cannot be used externally!
•
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 (e.g. manual 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).
Failure to follow the above safety measures can lead to severe injuries.
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
Failure to follow the above safety measures can lead to severe injuries.
