Safety engineering
Servo motors can perform speed-dependent safety functions for safe speed and / or safe
relative position monitoring in a drive system by Lenze inverters or Controllers. In case of
inverters, these functions are implemented by integrable safety modules and in case of
Controllers by the additionally required Safety Controller.
When planning systems/installations of this kind, always observe the following:
•
When using just one single feedback system in the environment of these safety
applications, the applicable safety engineering standard IEC 61800-5-2 (adjustable speed
electrical power drive systems - Part: 5-2: Safety requirements - Functional) stipulates
special requirements for the connection between feedback system and motor shaft.
•
This is due to the fact that two-channel safety systems at this point in the mechanical
system are actually designed as single-channel systems. If this mechanical connection is
designed with considerable overdimensioning, the standard permits exclusion of the fault
"encoder-shaft breakage" or "encoder-shaft slip". As such, acceleration limit values must
not be exceeded for the individual drive solutions.
You can find the limit values in the corresponding feedback data of the individual motor
ranges.
Speed-dependent safety functions
Examples of speed-dependent safety functions:
•
Safe stop 1 (SS1)
•
Safe operational stop (SOS)
•
Safely limited speed (SLS)
•
Safe maximum speed (SMS)
•
Safe direction (SDI) of motion
•
Operation mode selector (OMS) with confirmation (ES)
•
Safe speed monitor (SSM)
•
Safely limited increment (SLI)
