SAFEMASTER S
Standstill Monitor LH 5946 Sensorless Safety Standstill Detection
The sensorless safety related Standstill Monitor LH 5946 of the SAFEMASTER S
family recognizes direction-independent the standstill of motors without making use of
additional external sensors like encoder or proximity switch.The Standstill Detection is
directly achieved by monitoring the voltage at the motor connection terminals.
Particularly when it comes to access protection, where regular intervention during
production process is necessary, the sensorless Standstill Monitor LH 5946 can make
use of its strengths. When there is no dangerous movement from the motor anymore
the safety gate can be released within a very short time at detected standstill. Due to a
variable adjustment of the response value and reaction time on the device, an individual
adaption is possible.
Compared to solutions with time-controlled unlocking of safety gates, maintenance and
setup times can be minimized by use of the sensorless Standstill Monitor LH 5946 and
thus productivity can be improved.
