3.1.6 Use of qualified personnel
Use of qualified personnel 3- Sich Qualif. Personal
The products may only be assembled, installed, programmed, commis-
sioned, operated, maintained and decommissioned by competent per-
sons.
A competent person is someone who, because of their training, experi-
ence and current professional activity, has the specialist knowledge
required to test, assess and operate the work equipment, devices, sys-
tems, plant and machinery in accordance with the general standards
and guidelines for safety technology.
DANGER!
Risk from rotating motor after STO has been triggered!
The safety function STO switches the motor to torque-free. On
motors without a safe holding brake, moving parts present a
threat to life.
Use an additional mechanical measure to block the drives safely
(e.g. with the motor holding brake), particularly with suspended
loads.
DANGER!
Risk from non-safety-related activation of the motor holding
brake!
Activation of a holding brake via output BR+/BR- of the servo
amplifier is not safety-related. Depending on the application,
hazardous motor movements may cause serious injury or death.
A motor holding brake activated by the servo amplifier alone is
not suitable for personal protection.
Block the drive through an additional mechanical holding brake,
which is activated safely (e.g. with the safety card PMCprotego
S1).
