Protection Against Dangerous Movements

Dangerous movements can be caused by faulty control of connected motors. Some
common examples are:
● Improper or wrong wiring or cable connection
● Operator errors
● Wrong input of parameters before commissioning
● Malfunction of sensors and encoders
● Defective components
● Software or firmware errors
These errors can occur immediately after equipment is switched on or even after an un‐
specified time of trouble-free operation.
The monitoring functions in the components of the electric drive and control system will
normally be sufficient to avoid malfunction in the connected drives. Regarding personal
safety, especially the danger of injury and/or property damage, this alone cannot be re‐
lied upon to ensure complete safety. Until the integrated monitoring functions become
effective, it must be assumed in any case that faulty drive movements will occur. The
extent of faulty drive movements depends upon the type of control and the state of op‐
eration.
Dangerous movements! Danger to life, risk of injury, serious injury or property damage!
A risk assessment must be prepared for the installation or machine, with its specific
conditions, in which the components of the electric drive and control system are instal‐
led.
As a result of the risk assessment, the user must provide for monitoring functions and
higher-level measures on the installation side for personal safety. The safety regula‐
tions applicable to the installation or machine must be taken into consideration. Unin‐
tended machine movements or other malfunctions are possible if safety devices are
disabled, bypassed or not activated.
To avoid accidents, injury and/or property damage:
● Keep free and clear of the machine's range of motion and moving machine parts.
Prevent personnel from accidentally entering the machine's range of motion by us‐
ing, for example:
– Safety fences
– Safety guards
– Protective coverings
– Light barriers
● Make sure the safety fences and protective coverings are strong enough to resist
maximum possible kinetic energy.
