MCB 159 – select this option in the
configurator when ordering a new drive.
Not available for retrofit.
Reduce overall system cost,
improve flexibility and
increase productivity by
enabling operators to perform
maintenance safely, even
while the machine is still in
motion.
Additional safety
The VLT® Safety Option MCB 150/151
expands the integrated Safe Torque Off
(STO) function of the VLT® AutomationDrive. Use the Safe Stop 1 (SS1)
function to perform a controlled stop,
before removing torque. Use the Safely
Limited Speed (SLS) and Safe Maximum
Speed (SMS) functions to monitor
whether a specified speed is exceeded.
When the VLT® Safety Option MCB 151
is combined with the built-in
VLT® Sensorless Safety MCB 159 option,
an external sensor is no longer required
for safe speed monitoring.
Use flexible speed control in
upgraded or retrofitted applications.
Connect input devices – such as guard
locking switches, light curtains and
emergency stops – directly to the
module and eliminate the need for a
separate, dedicated safety controller.
Quick commissioning
and wiring
Visual instructions in VLT® Motion
Control Tool MCT 10 ensure both
fault- free wiring and that safety
parameters are correctly transferred
from the PC to the drive. The software
also offers a dynamic commissioning
report which can be used in the
technical file for the machine.

integrated into the
drive due to internal
databus connection
Feature Benefit
No need to power cycle the drive after
a demand on the safety system
Two logic safety inputs
Maintenance can be performed while the machine
is still in motion
Safe Torque Off (STO)
Integrated in the drive as standard
Safe Stop 1 (SS1)
Monitors deceleration and then
shuts off the torque
Safely Limited Speed (SLS)/
Safe Maximum Speed (SMS)
Monitors whether a specified velocity
is exceeded
– Minimized wear on the drive
– Provide redundancy without needing an
external safety module
– Minimized time and effort required for
service and installation work
– Increased productivity and availability
– Eliminates one or more power contactors
– Eliminates the need for additional feedback
monitoring
– Machine is restarted quickly and more simply

The VLT® Safety Option MCB 150/151
provides an intelligent, programmable
solution to meet EN IEC 61800-5-2
functional safety standards. It fits within
the drive and helps to reduce cabling,
requiring no cabinet space or external
power supply.
Connect active and passive sensors
directly to the pluggable safety
option over two channels. In many
applications you can then eliminate
external components, such as safety
switchgear, over-speed monitors, speed
encoders, and motor/mains contactors.
STOP
RT
There are different hardware variants
for HTL (MCB 151), sensorless operation (MCB 151 with MCB 159), and TTL
(MCB 150) encoder input. Each makes
use of the existing Safe Stop, terminal
37, via an external wire.
