•
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 classes with at least IP54 protection.
•
The proper cables and end-sleeves must be used
•
All cables that affect safety (i.e. control cables for the ENABLE_L and
ENABLE_H inputs) must be laid in a conduit outside of the control cabi-
net.
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 labeled
as reserved and cannot be laid externally!
•
When using the SS1 (Safe Stop 1) safety function, the typical turn-off de-
lay is 0.5 seconds. Subsequent actions that require the STO (Safe Torque
Off) function (i.e. manual access to the machine), can only be released af-
ter 1 second.
•
If external forces influence axes that are used with the STO safety func-
tion (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.
