Maximum Safety
Minimum Cost
In order to achieve the maximum safety
performance level PLe, a category 3 or 4
architecture must be used.
W
hat this means for a servo
system is that a second
method for measuring
speed is required, this is
usually achieved by fitting an additional
separate encoder or resolver to the
axis increasing the costs and complicity
to the system and set up process.
Due to its onboard safety card the
PMC Protego DS from Pilz is able
to measure the motor current to
determine its speed, this, combined
with the feedback signal provided by
any servo motor constitutes a category
4 architecture. This means that using
the PMC Protego DS drive and any
servo motor it is possible to achieve
PLe without any additional equipment.
The PMC Protego DS also has the
following Safe Motion Functions
included as standard: Safe Torque
off, Safe Stop 1, Safe Stop 2, Safe
Operating Stop, Safe Limited Speed,
Safe Speed Range, Safe Direction, Safe
Limited Increment, with Safe Braking
functions and Safe Limited Position
available as additional options.
With free configuration software the
PMC Protego DS is straight forward to
configure for motion tasks and safety
features alike.

Pilz launch new PUWER
Assessment service
Pilz Automation Technology has launched a new PUWER (Provision
and Use of Work Equipment Regulations) Assessment service that
aims to provide customers with an efficient yet detailed assessment
of their machinery to PUWER.
PUWER covers virtually all work equipment from something as basic
as a hand tool to a complex production line. Jamie Walton CMSE®
from Pilz Automation Technology explains, “The primary objective
of PUWER is to make the work environment safe for everyone using
or coming in contact with work equipment and machinery including
employees, employers, suppliers, contractors and anyone else.”
Pilz can inspect your machinery against PUWER and provide a
comprehensive report for each item of work equipment. For any
non conformance highlighted Pilz will conduct a risk evaluation
as specified in the standard EN ISO 12100:2010. Our PUWER
assessors can even come and present the findings and discuss any
questions you may have.
